25-year old center Ian Mahinmi is starting to really push Brendan Haywood for minutes.  Mahinmi has played in 19 games (0 starts) for the Mavericks so far this year and he is averaging 20.3 minutes, 8.1 points, 5.2 rebounds and 0.3 assists per game.  He is shooting 61.8% from the floor, which is pretty darn impressive even though most of the shots are coming from close range.  He will need to improve his free throw shooting as he is only hitting 64.7% so far this year and he gets to the line a lot due to his physical play.  The Mavericks are hoping that Mahinmi keeps improving as they are lacking in the paint both offensively and defensively right now.
