seriously rami? dirk is a bad defender as well. garnett averaged 14 and 7 if you didn't know. duncan averaged 18 and 10 and is on the wrong side of his career. pau gasol is made to look increasingly good because he plays next to kobe. stoudamire doesn't play defense at all, people have said it multiple times.
chris bosh plays with enough defensive intensity that dirk will not have to do anything. chris bosh is the best player on his team. and really the only piece that anyone would really want on the whole raptors roster. chris bosh had a starting lineup of calderon who's never proven anything, belleneli who's basically a spot up shooter, turkoglu who's robbing the franchise, him and barngani who has no defensive ability. chris bosh, especially as a second option, could contest for best power forward ever. right now who would you say that was? duncan? nowitzki? bird? bosh has the potential to be better than all three.
Karl Malone was the best PF ever, and I have no doubt of that in my mind. Bosh isn't that good... he's like a poor man's 2004 KG. He doesn't play with enough intensity on the defensive end. He isn't a good shot-blocker. He's a great offensive rebounder and that's how he gets most of his high-percentage shots. He takes too many outside shots as well for a PF. I guy like Stoudemire or even Boozer would serve us better on offense because both of those guys are pick-and-roll/low-post scorers - who can hit the 15 foot shot as a secondary weapon. Bosh likes to face you up and take you off-the-dribble, and is all over the place.
I think that all the current top PFs in the NBA has flaws. KG & TD are the best on defense but they are aging. Stoudemire, Nowitzki, Bosh, and Boozer the best scorers but none are good on defense...and the 2 best scorers (Nowitzki are Stoudemire) will only get you 7-9 rebounds.
Pau Gasol looked lost vs the Celtics in 2008, and got punished by Perkins. But honestly, I think that he is actually the most fundamentally-sound PF in the NBA. He may be a little soft, but he is naturally a finese type of player. Plus, I think that he has continued to improve since '08. It is unfair to say that Gasol only looks good because of Kobe... hell- Kobe looks better because of Gasol. I'm not saying he's the best PF, but that's just a bit unfair to imply that Kobe made him who he is. Before Pau, LAL as getting bounced by PHX every year. Pau puts up monster stats in a balanced, deadly offense... not easy to do.
