He is a bust in the sense that he was supposed to be the next Bill Russell or Tim Duncan and come in averaging 20/10. This was the expectation. He could still be an all-star center though, but the likelihood that he will be a HOF top big man seems less and less likely and his being chosen #1 seems like a mistake now.
If he didn't average 20 and 10 in College why would he come in and average 20 and 10 in the NBA as a rookie?... especially after not playing ball for over a year and still getting in shape from microfracture surgery?
He was supposed to be on Dwight Howard's level and have the potential to be better...
As I said... As a rookie Dwight averaged 12 points, 10 rebounds, 1.7 blocks in 33 minutes with 52% shooting.
As a rookie Greg is averaging 9 points, 7.2 rebounds and 1.2 blocks in 23 minutes with 57% shooting.
Project his minutes to 33 and he's getting 13 points, 10.3 rebounds, 1.7 blocks ....
Sounds about right. He needs to learn how to stay out of foul trouble (he likely will with time), get proper basketball stamina (probably will with time), regain his explosiveness (probably will with time) ... and he'll get the minutes to do more.
The guy only played a handful of games in College and missed most of his season because of a hand injury. I know he lead his team to the national title game, but I fail to see how that half-season makes him that further advanced than a high school senior jumping to the pros. We knew he was raw. And right now some of his early potential greatness is lost by the fact that he's still technically rehabbing from serious surgery. Way too early to say he's a "bust"... Al Jefferson didn't amount to crap until his 3rd season. If in a few years Greg is still hobbling around missing half his season and putting up mere double doubles... you can call him a bust, I guess.
Tim Duncan spent 4 years in College.
I don't care if Greg is a few years older than Dwight was when he entered the league... he's still a raw NBA rookie with only a handful of College games making him more "experienced" than Howard was.
