I think we agree more than disagree. 2005 was the bomb, but yeah, his career most definitely do not stack up.
McHale though, as much as you hate him, is up there for sure. I would say he has an argument as the 2nd best PF of all time, over Barkley, Garnett, Dirk or pedo. I would personally go Duncan, Dirk, Garnett, Barkley, Pedo, McHale, but an argument could be made that McHale was really that great. his post moves were second to none, including Hakeem, and he was great defensively. he was smart, and the only thing that wasn't elite in was passing. He could easily be a 1st option on a perennial contender, but then he played with Bird.
The Duncan/Manu 2005 duo really gets underrated. They were really dominant in their run, and they went up against some of the best defenses in modern NBA history and still produced. That said, Duncan really wasn't at his absolute prime, and was playing on two bum ankles. Going head to head, 03 Duncan would eat 05 Duncan alive.
