Anderson in my opinion is the player that is most similar to Bargnani. Although i think Anderson is a better shooter and a better rebounder. A better player.
The Magic last year and the Hornets this year mainly use Anderson as a spot up shooter. You would rarely see him post up, or try to beat his man off the dribble. Bargnani on the other hand is the opposite. He would spot up, you would also see him post up his guy, and sometimes create his own shot off the dribble.
Maybe the Raptors are trying to make him do things that Bargnani is not capable of doing. His low post game suck, and whenever he tries to beat his man off the dribble seems like he always ends up turning the ball over. Newsflash Dwane and Bryan, Andrea is no Dirk Nowitzki. Accept it already. Not even close really.
Raptors like i've been saying all the time in this forum should mainly use AB as a spot up shooter. Nothing else. Forget about the other things.
