Who will win the NBA Most Improved Player Award this season?

I think it should be Kevin Martin of the Sacramento Kings. He is averaging 20.8 PPG, 4.1 REB, and 2.1 AST on 49% FG and 85.1% FT. He averaged only 10.8 PPG, 3.6 REB, and 1.4 AST last season. Who would be your candidate for the NBA Most Improved Player Award?
