For a change, there are actually some very good posts in here.
I think before you get into who should win the MVP this year, you have to define the award. If it's the best individual performance by a player this year, I think LeBron and Kobe are really the only 2 possible choices. If it's the best player on a team that might win a championship, you almost eliminate those 2 from the running.
I like Steve Nash, I really do, but to be frank I don't quite understand the obsession with him these past 2 seasons. The Suns play offense differently than the rest of the league - this is due to their coach and his offensive approach, and yes, Nash fits into this system very well, but I'm confident that the Suns would be similar to what they are today with Jason Kidd, Billups, or a few other players running the point. Nash doesn't turn James Jones into a solid player, this offense does. Boris Diow was playing guard in Atlanta - Steve Nash hasn't transformed him, playing the proper position has, and the fact that he's more athletic than just about every player guarding him.
To say that the Lakers would be the #2 seed if he and Kobe traded teams is just plain stupid, and to say that the Suns have made an NBA record number of 3's because of Nash is ignoring the style the Suns play altogether.
Was Steve Nash an MVP candidate with the Mavericks? Not really, and I don't think he's magically gotten any better. I think this is the equivalent of the spread offense in NCAA football making QB's look much better than they are. Again, I'm not knocking Nash, he's a very good player, I just don't think he's all of a sudden the NBA MVP, this year or last year. This is also a system that made people think Q. Richardson was a good player, and he can't get off the bench for the Knicks, the biggest joke of a team in the NBA.
LeBron has the Cavs as the East's #4 seed, and Larry Hughes missed the majority of the 2nd half of the season (agree with some earlied posters about the Cavs-Heat game, one of the best games I've seen in years), and the Cav's roster isn't exactly all-star stocked.
Head to head, stat-wise, (ppg, rbg, apg, spg, bpg)
Kobe is 35.4/5.3/4.5/1.82/.38
LBJ is 31.4/7.6.6/1.56/.84
Points and Steals to Kobe, rebounds, assists, blocks to LeBron
FG% - Kobe is .449, LeBron is .480, FT% Kobe .849, LeBron .738
3pt% - Kobe is .346, LeBron is .335
Also keep in mind that Kobe averages 32 shots per 48 minutes, LeBron averages 26 - so I think it's fair to say that LeBron would at least match Kobe's ppg if he was jacking up 5 or 6 more shots a night.
Thus, my MVP votes are in this order: LeBron, Kobe, Dirk
