Basketball Prospectus' Bradford Doolittle has a system (dubbed ATH) designed to translate college and Euroleague stats to the NBA. This is apparently the first year it's being used, however, and so it's something of a test-run for the system.
ATH thinks DeJuan Blair has the best translation of any player in the draft, followed by Stephen Curry and then Blake Griffin. That doesn't mean that Doolittle thinks Blair or Curry is going to be better than Griffin, just that he has a more translatable game.
So how did the Rockets' acquisitions do in ATH?
Jermaine Taylor ranks as the system's 11th-best prospect. Chase Budinger comes in at #49, while Sergio Lllull is ranked #64 (it should be noted that Llull looks a lot better in Keven Pelton's system designed specifically for Euroleague players. There he's described as being a "potential steal" and as comparable to Deron Williams, Tony Parker, Delonte West, and Ray Allen. Weird).
Anyways, take all of that with a big heaping serving of salt. But it's still interesting stuff.
