Kelvin Cato is Ming's power forward. And, in a few years, when he's ready, Malik Badiane will be. Maurice Taylor isn't a banger, but he's a great bench player who can score at will in the post. Before his injury, Taylor was one of the rising stars in the NBA.
Bosh isn't ready to bang around with the big boys quite yet, but he is just a rookie. He could still grab 7 or 8 a game this year and be fine. After all, you can't teach size.
