Brown excelled at the left tackle position at Troy, allowing very few sacks. But he's not quite tall enough to stay outside in the NFL, and is a better run-blocker than pass-protector, so he projects as a guard. He will likely be taken toward the end of the second round by a team looking for depth on its line.
Brown has the initial quickness to jolt defenders back off the snap. He is solid in the run game, able to clear gaps and keep his man near him once engaged. Defenders rarely fall off his blocks. He is a good athlete when moving upfield, able to sink his hips to fit on a block, which should serve him well when pulling. He is competitive and works until he hears the whistle.
Brown didn't play guard in college, so he will face a learning curve as he transitions. He is only an average pass blocker. He has adequate footwork, but he can become too aggressive once in his set, causing him to fall forward and lose his balance, allowing defenders to beat him. If he were to try to play tackle in the NFL, he would run into trouble against the bigger, more athletic ends he'd face.
Future Hall of Famer
A once-in-a-generation type prospect who could change how his position is played
An impact player with the ability/intangibles to become a Pro Bowl player. Expect to start immediately except in a unique situation (i.e. behind a veteran starter).
A quality player who will contribute to the team early on and is expected to develop into a starter. A reliable player who brings value to the position.
A prospect with the ability to make team as a backup/role player. Needs to be a special teams contributor at applicable positions. Players in the high range of this category might have long-term potential.
A player with solid measurables, intangibles, college achievements, or a developing skill that warrants an opportunity in an NFL camp. In the right situation, he could earn a place on a 53-man roster, but most likely will be a practice squad player or a camp body.
