I think the more appropriate question is, "When was the last time we had an MVP award winner that we haven't bitched about?"
Then again, I'm not sure anyone is in the position to question any selection based upon the 1000 different criteria that exist for being the MVP. Nash won it two consecutive years in a row because he "was the most valuable to his team." Dirk was the best player on the best regular season team. KG won it for the same reason as Dirk. Jordan won it because he was the best player in the game. Kobe is the best player on the planet to have never won an MVP award, and so on. Of course, that doesn't give enough credit to Kobe, who's the best player in the game, and is what the award is synonymous for.
