Have you got proof to back up the no defence stance everyone is vomitting out?
I don't think Duncan will win it, due to emergence of Ginobili as a superstar and Parker as well.
Garnett won't win it, unless they go on some crazy ass winning streak.
He gives up 48% shooting to his opponents, that would be fine if he was playing C or PF, but he plays PG. The Suns opponents shoot 7% better when he's on the floor as opposed to when he's off, and they get 9% more assists when he's on the floor as opposed to off, which is likely due to them getting less dribble penetration.
Ginobili isn't a superstar, just an All-Star, but I don't think Nash won't [not will] win it because of the emergence of Amare as a top 10-15 player in the league. The Suns have 3 top 20-25 players in the league in Nash, Amare, and Marion, with Amare and Nash being in the top 10-15.
Parker is good, but at best a in the 30's - 40's in terms of ranking among players in the league.
They wouldn't be as good without Marion and Amare, for sure, but the Suns have a lot of offensive firepower. Nash is the one that runs the plays, and the other guys are there to score. If they lose a player, there's still other guys that can step up.
The only losses that would hurt the Suns are Marion, Amare, and Nash. Joe Johnson and Q-Rich can be replaced by Jackson, and for the short term they can survive without them for the most part.
If Marion goes down, they become an even worse defensive rebounding team that they already are. Their defense isn't near bad at all like some people think, it's actually above average to good as a team, but their defensive rebounding is bad.
Also with Marion out, it takes away the bulk of their steals which lead to fastbreak points, and it also hurts their interior defense because of his shot blocking.
With Amare out it might be even worse, Jake Voskuhl didn't average 24 points a game after Marbury left, and Steven Hunter is offensively challenged. If Amare goes down, they have no inside scoring at all, they don't have his shot blocking inside, their defensive rebounding suffers again as Marion isn't going to be averaging 15 rebounds a game, and they become a strictly jumpshooting team. Their team FG% won't be #2 in the league anymore, they'll be shooting 44% or so. It will also mean Q-Rich will get more shots, which as we all know is never a good thing.
