Jamon Brown played his senior season at Louisville listed at 6'6", 326. While not quite Rob Havenstein territory (6'8", 333), that is still a mammoth of a man. And yes, those 'official' heights and weights listed in the programs are inflated. Brown's official measurables at the combine were 6'4", 323.
Brown is known for (SURPRISE!) his tenacity in the run game. He takes the fight to his opponent, sometimes with a little too much vigor. A little slow on the uptake at times, he can be beated with stunts and has also had some conditioning issues.
