Hindsight is 20/20ish. Here's how I would rank the rookies after their first season. A few of these players have yet to see extended minutes such as Gillinari and Alexander but I'm ranking them based on my projection for their NBA future.
01 Derrick Rose
02 Russell Westbrook
03 OJ Mayo
04 Michael Beasley
05 Anthony Randolph
06 Brook Lopez
07 Eric Gordan
08 Brandon Rush
09 Marresse Speights
10 Kevin Love
11 Courtney Lee
12 Jason Thompson
13 DJ Augustine
14 Jerryd Bayless
15 Danilo Gallinari
16 Joe Alexander
17 Roy Hibbert
18 Nicolas Batum
19 Mario Chalmers
20 JaVale McGee
