I've seen a lot of posts and comments that imply or flat out state that Nate is a very poor coach at developing young players(especially point guards). However, I think the majority of the evidence shows that Nate is very good at developing young players. His deficiency may lie in working with under-confident players, but not in player development.
If you were to describe a coach whose record with players he worked with ,with fewer than 4 years in the league was:
1 multiple all-star
3rd year player just below the all-star line but in the top 10 for his position
2nd year player who is a solid starter and potential all-star
2nd year player who may not fulfill potential to start at PG, but definitely can be a 6th man in this league
2 2nd round picks who after 1 season looks like they're going to fill out to be fine roll-players
2nd year player who put up dominating numbers before going out due to injury
2nd year player who showed sharp decline from first year, may be due to injuries
1 player who developed into a starting point-guard in a different system after the trade
1 player traded away who couldn't get minutes in Sacramento
5th year player who has become a solid bench player but may never reach potential
So Nates shooting 60-70% with developing draft picks.
Now a lot of the credit can be given to Kevin for astute drafting, but I think when people talk about Nates failure's as a developmental coach they're missing all his successes. Roy, LaMarcus, Batum, Bayless, Oden, Cunningham and Pendegraph are players that Nate has successfully developed. If they stay healthy and continue along the path they are you could be looking at the starters and key role-players for a championship team. All developed by one coach.
Sure he failed to turn Sergio into gold, but nobody has. Nate may also have failed to get Martel to his potential, however some of that is due to loss of playing time to Batum and a stress fracture. If Martel had started the last two years we may have seen a different player entirely. And Rudy may be leaving Portland, but I think the jury is still out on Rudy. I will say that Jarrett Jack was probably a failure on our organization's part.
But this is still a pretty awesome record for player development.
