It's easy to go with the leading point scorer as the MVP, and rightfully so. I imagine having a leading point scorer in the entire league on your team would go a seriously long way in your team's success. However, I do want to highlight some other players that would be quite compelling beyond current point leader Doug Weight.
Games Rating, a valid metric by all regards, would indicate James Howlett as the premier player. Sure, he doesn't have the explosive points total that Mr. Weight has, but 50 points in 52 games is still quite remarkable while playing an incredibly well rounded game. His Game Ratings are all in the 80s and I imagine his play really helps the structure of that Grizzlies team by quite some bit.
You could also potentially make the case for a defenseman as well like Boofa Benson or Cadmael Ixazaluoh that all play incredibly reliable defense. However, given that by convention it usually goes to a big splash name, I imagine that Mr. Weight still remains the favorite to take home the league MVP award
