Coach McMillan Wonders If Guards Make Better Coaches

Mike Rice and Nate McMillan sitting side-by-side on a couch in a dark home theatre.  

Yes, that's the premise of a new television program from Comcast Sports Northwest.  A little creepy, sure, but oddly enthralling as the viewer gets to watch and listen as two coaches break down game tape.

In an episode that aired (re-aired?) last night, the two coaches raised a few questions:

  • Do former guards make the best NBA head coaches?
  • When was the last time a center was a successful head coach?

Thanks to Basketball Reference's data I ran a simple analysis to answer these questions.  

The answers aren't particularly shocking but are hopefully more interesting than the 385th iteration of an Andre Miller - to - Portland rumor.

Click through for the results.

Star-divide

----------------

Note: Basketball Reference lists regular season stats  for 285 NBA head coaches.  The following analysis is limited to the 112 of these coaches that have 100 or more wins in their NBA careers.  Coachers are considered to be former players if they played in the NBA, ABA or the BAA (precursor to the NBA). Playoff results are not included.

----------------

Before we look at which position enjoys the most success as an NBA Head Coach, we should briefly look first at a larger dichotomy: former players vs. non-former players.

Are Former NBA/ABA Players Better Coaches Than Non-Former Players?

  • There are 112 NBA coaches with at least 100 wins. 68 are former players; 44 are non-former players. The following table compares the two groups' wins/losses/winning percentage.
Nmchart1_medium
  • Of the top 25 winningest head coaches, 14 are former players, 11 are non-former players.
  • The top 6 most winningest coaches in NBA history are former players. 
  • 7 of the top 10 most winningest coaches are former players.
  • Note: both groups listed above are able to have >50% winning percentages because this includes only those coaches with >100 wins. As you might imagine, coaches with <100 wins helped boost the winning percentages of both groups shown above. 

Which position makes the best NBA head coach?

OK, now to tackle Coach McMillan's questions.

As stated, there are 68 NBA coaches with more than 100 wins. The following table breaks these 68 coaches down into their positions and compares their wins/losses and winning percentage by position. All positional designations were pulled from Basketball-Reference and/or wikipedia.

Nmchart2_medium 

  • Clearly, former guards have overwhelmingly dominated other positions.
  • Interestingly, though, forwards have actually outperformed all other positions when it comes to winning percentage: 57%.  

The following chart condenses the data slightly to help show just how dominant guards have been as coaches.  

Nmchart3_medium

  • For NBA coaches that were former players and have 100 or more victories, former guards have more wins and more games coached than all other positions combined.

Are there any Centers coaching? How successful have Centers been?

  • Only 5 true centers have more than 100 career victories: Bill Russell, Joe Lapchick, Wes Unseld, Dave Cowens and Harry Gallatin.  
  • From that list, Only Unseld (last coached in 1994) and Cowens (last coached in 2001) could be considered "modern." 
  • The "forward/center" designation list includes Dan Issel, Tom Heinsohn, Dolph Schayes and Ray Scott in case you feel there was a center's name missing from the list above. 
  • Issel is by far the most "modern" name from that list, having last coached in 2002.

Nate Notes

  • Coach McMillan is currently 37th on the list of most NBA victories as a head coach.  
  • Only 11 former guards have more career wins than Coach McMillan: Lenny Wilkens, Larry Brown, George Karl, Rick Adelman, Gene Shue, Mike Dunleavy, Al Attles, KC Jones, Kevin Loughery, Larry Costello, Doc Rivers.

Conclusions

Among NBA Coaches with >100 victories...

  • Former players have outperformend non-players. 
Among NBA Coaches with >100 victories that were former players...
  • More former guards have had long, successful NBA coaching careers than any other position.
  • Former forwards enjoy a better winning percentage than any other position. 
  • Former centers are a rare breed with very little recent success.

But interesting work

Yeah, probably most people assume guards have a better understanding of the finesses of the game. The next center who becomes a head coach is probably Patrick Ewing, whereas a number of guards are lining up. Among currently active players, I think I could see Fisher as the most likely future head coach.

Additionally

I would say he’s a people motivator but how does it break down with assistants? Are his assistants previous guards? I honestly don’t know, but has they seem to handle more pregame strategy and and he manages the personalities…

I’d be interested to see the break down with assistants to the winners as well.

the ket question

Is whether the differences are ‘statistically significant’ in a scientific or meaningful way. I’d check your work, Ben, but I’m on my phone. Anybody else want to run some independent t-tests?

i think you’re shooting for bigger conclusions than i’ve drawn here and asking a different, perhaps deeper, question than those i set out to answer.

by Ben Golliver on Jul 22, 2009 5:42 PM PDT up reply actions  

But you do not really answer your own question Ben.

The question you have answered is “What position player is most likely to become a head coach.” or “Which position has contributed the most head coaches.”

The winning percentages indicate that it doesn’t really matter what position you played, except for center. All the others have percentages that are relatively similar.

That guards make up the majority of former players becoming head coaches and dominate the numbers in terms of wins only infers that guards tend to make better coaches.

You’d need to know the standard deviation from each population in order to run t-tests.

Didn't run any numbers

But at a glance they sure don’t look significant. Except of course that smaller positions are more likely to coach.

I think it’s safe to assume that the average guard would make a much better coach than the average center, BUT this is accounted for by who gets coaching jobs. That weeds out all the centers who would make bad coaches.

Keep in mind that everything I know about basketball I learned on Blazers Edge.

One question

How many centers and forwards has been hired as coaches?

If one center was hired to ten guards than that is not a fair analysis.

Maybe that is why centers don’t post up anymore; guards would rather shoot the ball or pass it out to a 3 pt shooter. There is no reason for centers to post up if they are not going to get the entrée pass anyway.

Hmmmm

who cares really who the coach is or what position he played (I have a lot of respect for Nate, by the way) as long as his team wins? Just a thought

by Cory2669 on Jul 22, 2009 5:38 PM PDT reply actions  

You could also ask, does a coach really develop players, or do they just realize their natural potential and he needs to manage them efficiently (which is a strength of Jackson). Maybe the influence on role players is bigger. Yet while all players develop somewhat no coach can suddenly develop a LeBron or Kobe or Jordan or Shaq out of a dud. And even players who took a longer time to develop into stars, like Billups, are usually influenced by more than one coach (in Billups’ case it were about 4 in the NBA alone, not counting college).

by Norsktroll on Jul 22, 2009 5:47 PM PDT up reply actions  

These days I doubt coaches have much influence or effect on developing players.

Whether or not a player develops is most likely determined by;

 - how hard he works at improving his game

 - how much playing time (i.e. game experience) he gets

 - how intelligent he is

coaches – head or otherwise – can show players technique and give advice, but it is usually up to the player to take advantage of that and then to take it to another level.

I'd take this as evidence that guards do make better head coaches

I’d assume that a former nba player that is not a head coach is worse coach than a former nba player that has won at least 100 games… since coaching is a higher paying job than most ex players have.

by PoliSam on Jul 22, 2009 5:40 PM PDT reply actions  

biggest problem with that argument would be

if the pool of former nba guards is larger than the pool of other positions…. I suppose that could be true, depending on how the player-positions are counted and other factors, but probably not.

Don't know if I agree with your (vague) definition of "modern"

I dont see that the guards are 'better'

I dont take away from your data that guards are ‘better’ coaches, only that there are more of them. The % of player/non-player and each position is relatively equal. The quantity of the guards is more, but the quality is pretty much the same.

by ItsMrHarris2u on Jul 22, 2009 7:40 PM PDT reply actions  

Statistically it makes sense G's are better coaches than F's and C's

Because statistically there are more 6’4" and shorter humans on the planet than 6’5" and taller humans. Since the pool of possible coaches is smaller, we can expect the overall number of F and C sized coaches to be proportionately smaller. This assumes a correlation between sucessful coaching and population, but you’d also have to consider the number of teams in a given league too.

This assumes there are fewer super tall people than moderatly tall people, which I feel isn’t too far of a stretch.

This also explains why 7’3" stiffs like Thabeet get nba jobs. There aren’t many of them on the planet.

Can you dig it?

I don't dig it

If we assume that ex-players have coached 5/8 of all games, and that centers comprise roughly 1/5 of the player population, if it’s just random, you should see 1/8 of these games coached by ex-centers (or 12.5%).

Instead, it’s 2.3 thousand / 80 thousand. That’s about 2.9%. Way less than 12.5%.

Your premise would make sense if the percentage of players who become coaches equalled the percentage of players in the whole population. Obviously, that percentage is much bigger.

Think of this way: if Thabeet somehow became an NBA guard, his chances of coaching will truly increase. (Now that would be a sight to see.)

by chnews on Jul 22, 2009 9:17 PM PDT up reply actions  

Think total population

Not just nba population. I think you’ll find yourself agreeing with me then.

The ability to coach isn’t tied to hight or basketball skill. If you examine the pools of former guards who are coaches, and F’s and C’s who are coaches I’d bet the percentage of coaches is about equal in terms of sucess rate. Since there are exponentially more short people, I don’t think its fair to include them mathmatically.

My theory

6’9" and taller guys are tired of the NBA travel by the end of their playing careers and have no desire to spend 6 months per/year on the road, even with today’s “charter airplane” accomodations

When reached 39 years of following Portland basketball you have, be as passionate of the Trail Blazers you will not!

by two4larue on Jul 22, 2009 10:01 PM PDT up reply actions  

Yes

The average 6’0" NBA player is definitely way smarter than the average 7’0" player, just like they are way faster and way more skilled. It’s all about the numbers, just like you say. If you’re 6’0", you have to be really good to make it. If you’re 7’0", you only have to be moderately good.

Keep in mind that everything I know about basketball I learned on Blazers Edge.

Depends what you mean by "success"

Among ex-players, guards are coaching many more games than their numbers in the players ranks would suggest. It’s clearly much more likely you will be hired if you’re a guard, even if we assume they account for 2/5 (or even 1/2) of the player pool.

But among ex-players’ winning percentages, ex-guards aren’t winning more. I’m not convinced that means anything: i would guess that crappy teams are even more likely to hire ex-guards, but who knows. Teams measure success lots of ways, including who is willing to work for less $.

In terms of hiring coaches: there is no doubt that guard bias exists, assuming an ex-player is hired.

by chnews on Jul 22, 2009 9:56 PM PDT reply actions  

I firmly believe that guards make better basketball coaches in the same way that catchers make better baseball managers. When you run the show on the field of play, you have relevant experience and/or personality to be able to run the show off the field.

But as this exercise shows, it is difficult to prove statistically within the highly selective and tiny pool of NBA coaching positions.

What can be shown is what chnews said – they are hired more often.

Just the law of averages coming into play

Guards are at 52% win/loss simply because of their far greater and significant sample size of coaches and games played. If there were a greater sample size of forwards and centers as NBA coaches I believe you too would find their win/loss percentage gravitating more towards the 52% mark.

It would be reasonable to infer that more former guards are chosen as coaches due to their experience on-court playing the role of floor general. The guard position more than any other position traditionally (i.e. point forwards are a modern day anomaly) is designed to steer and direct the entire team throughout the game.

But to suggest that IQ is inversely proportionate to height is just lame… some of the dumbest dudes I know are on the short side. Purely anecdotal, not statistical, but I seriously don’t buy that tall guys are unintelligent.

This was neat

I have two questions.

Are point guard coaches similar to catcher coaches in MLB?

Is Bill Laimbeer the most successful former center coach? He won three championships with the Detroit Shock.

Statistical Skewing

So if you have a couple of really extreme good and bad apples, do you take those out?

Phil Jackson has one a lot and is likely a dot all by himself. where do all the other dots sit?

Isiah, is he a dot by himself or does he have a lot of company? what does the data look like when you remove those extremes? Is there a middle ground or is there a cluster on each side of the spectrum?

Does perception influence the data? The conventional wisdom that guards make better coaches, does that mean that people only higher guards and thus the higher percentage of guards as coaches?

What percentage of coaches from each of the sections would be “upper tiered”? Jackson would be. Poppavich would be. What percentage would be average? what percentage would be below average?

Another Idea for a Comcast Sports Northwest show...

Travis Outlaw and Mike Rice in “Fishing With Super-Trout”.

Could you imagine Travis Outlaw and Mike Rice hosting a fishing show together? Where would the conversation take us!?! I could listen to Travis and Mike talk about anything – Outlaw’s game winning shots, life in Starksville, Mississippi, jumping from prep-to-pro, nuclear physics, etc and it would be awesome.

Fishing could take place during off hours, like…

4:30 – 6:30am – Filming “Fishing with Super-Trout” with Mike Rice
6:35 – 7:45am – Eat breakfast and get ready for workouts
8:00 – 11:45am – Practice two-dribble pull-up fadeaway jumpers from 19 feet
12:00 – 1:00pm – Lunch
1:15 – 8:00pm – Corner three-pointers
8:45pm – 10:00pm – Night “Fishing with Super-Trout” with Mike Rice

Act like you’re not intrigued by “Fishing with Super-Trout”…

“Travis, how did you wind up using peanut butter and jelly sandwiches for bait?”
“Well, coach told me – you need to use bait when you’re fishing, sumthin’ fish will really like…”

An interesting side question

might be, how many of these successful former players turned coach were good players? For example, Larry Brown, Bill Russell, Lenny Wilkens are examples of pretty good players who became pretty good coaches. Rick Adelman, Phil Jackson, Pat Riley are guys who weren’t very good players, but are good coaches. In other sports, usually the best players make lousy coaches, and the worst players are better coaches. Perhaps it is because the lesser players have to work at it more. Just a superficial guess.

Some coaches were too old by the time the league started to ever play

I don’t know if that would make any difference, but it could skew things. It might help to only look at the last 20 years.

Of course, Red Aurbach (5’9, asthma) was never going to be a pro player, even if it was an option at the time.
