I personally find Okafor's biggest issue is his stamina. Dude looks gassed after like 2 minutes out there and a lack of stamina affects all aspects of the game. If you gassed you not gonna be able to help on defense and think correctly on the court..he's also a lot more passive on offensive this year probably cause of a lack of energy to execute his moves on a consistent basis. He needs to work on his stamina first and foremost. It's even stranger because dude isn't fat like at all especially compared to his Duke days, dude looks slim. I dunno if its the knee injury that messed up his ability to work on his stamina over the off-season but its a fkin problem.
