Yes he is a great defender, but he's playing alongside the best defensive PF in the game, in a great defensive system. That makes his job easier.
In offense, nobody defends on him because he's got 3 HOFamers + a good PG around. He isn't a great rebounder and he is the slower guy in the ligue ahead of Yao. LOL.
No way I'll give him 60M/5 years
