Statistically he's in the middle of the pack of PFs in the league and if you look at his statistical production from his first two seasons in the NBA and compare it to the rest of his career, they're actually identical. That is, he had PERs of 16.8 and 18.9 his first two seasons as a Clipper, and his best two statistical seasons since then have been 18.5 in Miami and 17.3 in LA in 05, with a whopping 14.0 this year, a season in which he has generally been horribly inconsistent and offensively inept when it matters most.
With Bynum out he's averaging 13 ppg on 35% shooting.
