I would stay away from McAdoo. He doesn't do a single above average thing besides maybe rebounding. Going way back, he reminds me of another highly regarded prepster from 1994, Jerod Ward, in that he plays college ball like the game is too fast and big for him. In his freshman season, he shot more airballs from 10 to 15 off open jumpers than I had ever seen in my life. He looked more comfortable as a starter during the ACC tournament so I thought his struggles were related to coming off the bench for the first time. Instead, he looks just as rushed his sophomore season as his freshman one.
While he looks like he would be an ideal roll/pop man in the NBA, he's actually an awful finisher at the rim and his outside shot is erratic. If he can't finish effectively at the rim against college big men, how he's going to fare against NBA big guys? Just like with his airballs, I've never seen a player as consistently embarrassed trying to finish around the rim as he has. He's been on the wrong side of so many highlight reel blocks where he's reared back and was about to flush it and the defender got all palm on the ball and wiped him out. It's really mystifying because he has genuinely good physical gifts yet over and over he's treated like a caucasian scrub venturing too far out of his depth.
On a side-note, if professional basketball doesn't work out for him, he could make a lot of money off his voice. He has a fantastic set of deep, vibrant pipes.
