Bosh used to be pretty sick. Now he's a glorified role player in a system that doesn't make use of his talent.
Bosh had four consecutive 22+ ppg seasons and then a 24 ppg season in his last year in Toronto. 3 seasons over 10 rpg and another over 9 rpg, which is worth mentioning because Aldridge has never cracked the 9 rpg barrier. Aldridge is close, and he doesn't play on teams as bad as Bosh's Toronto teams, but I wouldn't say he's lived up to Bosh in his hey day.
Also, Bosh is become an impact defensive player on Miami, playing C for long stretches and anchoring the defense.
