They also had a further breakdown of their MVP vote: http://sports.espn.go.com/nba/news/story?page=MVP10 LeBron James: 90 points (18-first place votes) Kevin Durant: 55 (6 second-place votes, 7 third, 5 fourth) Dwight Howard: 46 (5 second-place votes, 4 third, 6 fourth, 2 fifth) Kobe Bryant: 40 (5 second-place votes, 3 third, 4 fourth, 3 fifth) Dwyane Wade: 20 (2 second-place votes, 2 third, 1 fourth, 4 fifth) Carmelo Anthony: 10 (1 third-place vote, 2 fourth, 3 fifth) Dirk Nowitzki: 5 (5 fifth-place votes) Deron Williams: 3 (1 third-place vote) Steve Nash: 1 (1 fifth-place vote)
I guess being the starting point guard for a team that exceeded expectations and actually won some games isn't worth much to most voters.
Guessing you're referring to Jennings...I wouldn't say he's the primary reason Bucks are playing good. I would attribute that to the return of Bogut, the defensive minded coaching of Skiles, and the trade for Salmons. Jennings is somewhere in their with his solid playmaking skills, but man his shooting is horrendeous and he's destroyed them at the end of some close games.
