THE GOOD, THE BAD
Were the early jumps worth it? As they say, hindsight is 20-20, and for a bunch of the players listed, they probably wish they had stayed another season, if not two. But there's still time for several of the guys to prove the naysayers wrong.

And it's not like the decision to leave early dooms everyone, as Jamal Crawford, Jason Richardson, Zach Randolph, Kris Humphries, Mike Conley and Eric Gordon all are enjoying successful careers.

Humphries gives Kosta Koufos and Byron Mullens, among others, hope. Things didn't click right away for the Humphries, playing for three franchises before receiving his first real shot, and now the one-and-done Gopher is one of the league's most dominant rebounders and a double-double machine.

Can't wait to see where Leonard and Sullinger land in a couple months. We'll find out June 28 at the 2012 NBA Draft.
