Here's my view of the MVP debate. I am a devoted Detroit Pistons fan, but I'm trying my best not to be biased in any way.
Steve Nash has been amazing, don't get me wrong, but I'm sick of this arguement that he has nobody around him. Shawn Marion was a 20-and-10 guy, All-Star and Olympian before Steve Nash came back to Phoenix, and he is one of the best players in the world, no question. He's been consistently doing what he does for years. And while he might have help scoring his 13 points, Boris Diaw doesn't get his 6 rebounds and 6 assists per game (while playing mostly Centre at 6'8") because of Steve Nash, it's because of himself. And I'm sure Steve Nash isn't helping Raja Bell defend the likes of Kobe Bryant either.
Dirk Nowitzki does have people around him too. Jerry Stackhouse anyone? Sure, he's declining now, but he was a 29ppg scorer in Detroit and an All-Star just a few seasons ago. Jason Terry is no slouch either, being a leading player for the Hawks for a number of years. One of the League's most underrated players in Josh Howard is pretty helpful also.
And I believe LeBron James has a 2-time All-Star centre in Zydrunas Ilgauskas, plus a Drew Gooden, who averages almost a double-double, and one of the best 6th men in the league, Donyell Marshall.
Kobe Bryant also has a 15-10-and-5 guy in Lamar Odom (who people always forget), plus a handy player in Smush Parker. They also still have a guy who was a starter/vital cog during their recent glory years, Devean George.
So, in my opinion, the award should go to the best player on the winningest team, because that's what the League should be about, winning. Therefore, the 2005-06 NBA MVP should be Chauncey Billups of the Detroit Pistons.
