No Doubt in my opinion, has done a great career and he is an All Star Caliber. Perk is a Role Player, just a good defender in c's System. but is offense is terrible, he don't have a mid range shot, don't have ball handling. Is a Solid Rebounder, but a normal player.
Jermaine is delicate and his knees are crystal, but he is a better Player in every foundamental. I Think that Jermaine is the best "blocker" of the nba
