I have read where Chad Ford of ESPN considers McGee another Andray Blatche (I fail to see what is wrong with that, on the court). If you look at the dozens of highlights on McGee you will find that this guy, like Blatche, can handle the ball, run the floor, and shoot, like a guard. He is as agile as anyone on the team. The major difference between McGee and Blatche it seems is
1) McGee looks to be more mature and has proven he is willing to work on his strenght and conditioning (has already added over 8 pounds of muscle since end of college season)
2) McGee is more of a defensive force. He can take over games once he gets his defensive footwork down with his shot blocking
If you really want to see what Wizards will have, maybe as soon as the middle of next season, take a look at Tyson Chandler of the Hornets, both phtysical build and playing style for what the Wizard would need from him next year. You can not deny this guy's physical skill set and that is something you can not learn.
