Udonis Haslem

Power forward for the 2006 NBA champ Miami Heat. He is a scrappy player known for his agressive rebounding and underrated defence. Although he is undersized he has emerged as one of the best forwards in the game. He shoots a high percentage from the field and plays off of Shaq very well. When Shaq gets doubled he passes it to Haslem who hits his mid range jumpers. He is a big help to Shaq down low.

Udonis Haslem plain shut down Rasheed Wallace during the Eastern Conference Finals and wore down Dirk during the NBA finals.
