Ok, there's 3 (shortened) facts listed here, so click the link for the full article.
3.) College stat-heads have become obsessed with efficiency ratings. But while efficiency matters, assertiveness is even more critical if a player wants to get drafted. First round picks used an average of 26% of their team’s possessions when on the floor while second round picks use an average of 24% of their team’s possessions. From 2003 to 2011, only seven players used less than 20% of their team’s possessions and were selected in the first round.
4.) Efficiency is less important than you might think. Players like John Wall and OJ Mayo didn’t actually have efficient seasons as they departed college. But NBA scouts like the fact that those players were allowed to develop their game. John Calipari didn’t hold John Wall- he allowed Wall to make some mistakes and learn and get better. Wall’s 109.2 ORtg and Mayo’s 106.9 ORtg don’t sound like the ratings of elite players, but there was enough information on these players to push them to the top of the draft.
5.) Overall, draft position is at least somewhat related to a player’s statistics, but the stats certainly aren’t everything. Players with great usage rates and efficiency stats can slip, particularly if they lack size for their NBA position. A 6’7" forward that dominates in college can easily slip behind a 6’11" forward with worse college stats, because ultimately, you can’t make a player grow taller.
