I've said it before, I've said it again...MVP is such an ambiguous term. Everyone seems to have different criteria for what they think it should encapsulate, so how can you really grade it properly. Is it the most dominant player that year...does team success have something to do with it?
Personally...I think it should be called, TBP (The Best Player). Forget how the team did. Who had the most dominant statistical season. Period. A dominant player shouldn't be penalized because his team doesn't have what it takes. If you want to award players on great teams then create an award for ensemble cast.
