How come Allen Iverson doesn't worth the same as the top players?

Iverson is my favorite player but he has to be surrounded by defensive players and be in the perfect situation for him to be successful. PG Allen Iverson SG Raja Bell SF Gerald Wallace PF Boris Diaw C Tyson Chandler He need to go to the bobcats because chandler, wallace, and bell are all really good defenders and iverson would average 25 ppg again
