Davis is still pretty weak, but he'll get there, he's still only 21. Only real issue is he's 21 and already has that dreaded when healthy moniker.
Watch the video on nbastats http://stats.nba.com/player/#!/203076/stats/ click on blocks and you can watch video of all of AD's blocks. 2 or 3 of them he waved at the ball, the shot missed, and he got credited with a block.
The only injury he had last year was a broken hand, I believe. He doesn't have some nagging chronic injury like everyone believes he does.
Wrote my thoughts on them as a potential playoff team, and always looking for feedback, if anyone is willing to give it a read.
