I think in terms of style of play, Ben Wallace is easily the closest. Hakim Warrick is the inverse Amir. They just have an identical build. If you combined their strengths you'd have a very talented player on both ends of the floor that doesn't have much of a head for the game.... As for the Ben comparison.... Ben is/was without question much smarter and stronger, but that's the difference between a role player and a franchise changing player like Ben. Both impact the game almost solely with all out effort. Both are athletic and quick for "Big" men. Amir has the better shot by a mile, but he doesn't do a good job of finding open spots in order to utilize it. And even though Ben was "pretty good" defensively man-to-man, it certainly wasn't his strong point on defense, much like AJ. The biggest difference is BBall IQ, and Ben's incredible ability to alter shots without picking up fouls (in his prime). To be fair, at Amir's age today, Ben was playing for Virginia Union still, and had 6 years left before his 1st DPOY season in Detroit, but I don't think the instincts (or frame) can be taught in any amount of time. For comparison sake: Ben's 2nd year (23 yrs old): 16.8mpg, 3.1ppg (51.8% FG), 35.7% FT, 4.8rpg, 1.1bpg, 1.7pf Amir this year (21 yrs old): 16.1mpg, 3.9ppg (59.3% FG), 70.8% FT, 4.3rpg, 1.0bpg, 3.2pf The glaring difference is personal fouls (There's a shocker!).
