ESPN article using some statistical metrics.  It takes a players non-NBA numbers, then uses their athletic measurements to estimate how well that production is likely to translate to the NBA:
http://insider.espn.go.com/nba/draft201 ... ts-numbersSome interesting ratings and comments:
#1 Nerlens Noel
#2 Cody Zeller
#6 Steven Adams
#10 Victor Oladipo
#11 C.J. McCollum
#18 Kelly Olynky
#28 Shabazz Muammad
#30 Rudy Gobert
#38 Kentavious Caldwell-Pope
From a per-possession-efficiency standpoint, Zeller ranks as the best prospect on the board. The excellent athletic markers he displayed at the combine hold up statistically, as he's got the third-best ATH rating in this class. Zeller lags in the skill area in terms of outside shooting and passing, but I'm still convinced Zeller is underrated in the prospect rankings I've seen.
Adams is one of the big risers on the board in terms of disconnect between metrics and scouting rankings. He's got the best-projected rookie rates in 2-point percentage, overall rebound percentage and block percentage. Yes, his block projection is even a hair better than Noel's. Body type has a lot to do with that. Consider Anthony Davis, who projected to lap the field in rookie block rate last year. He indeed was an excellent shot-blocker, but Andre Drummond and Festus Ezeli both put up better rates. Despite a foul rate that looks problematic, Adams is a worthy project.
Caldwell-Pope has good stand-still shooting indicators but is held back by a poor defensive translation that conflicts with scouting reports.
Last years rating using the same system:

Liked Lillard
Not a fan of Leonard
But overall, this rating system seems to have done a better job ranking the rookies than the draft itself, so it is worth considering.
