I say this is a good bunch of dudes, but no one thinks Duncan is the best? He's argueably the most consitant baller in the NBA, and he's a good presence, they say he's a very funny dude, yet serious.
I still think Garnett, because he's a good leader like Duncan, just he's so much more versitile than anyone in the league, bar none. He can play all five positions, he's the best passing 7 footer since Wilt Chamberlain, and he can dunk, rebound and block shots. He's currently holding the record for most 20-10-5 seasons and holds the record for most consecutive 20-10-5 seasons, with 6 and counting. Larry Bird held it before he did, but Garnett has sharttered it. I think Garnett has led the league in efficiency for the last 5 years aswell.
