It's the first major event on the player evaluation run-up to the draft, the Senior Bowl. And it's a great chance for the 110 players assembled in Mobile to burnish their resumes, as the evaluation season heats up.

After spending the week watching most of the practices by the North and the South teams, we've narrowed it down to three players to keep an eye on during the game, which airs at 4 p.m. ET on NFL Network.

SENIOR BOWL: Rosters | History | Hall of Fame

1. WR SAMMIE COATES AUBURN (#18 SOUTH)

He's dynamic and explosive. And he's just as confident as you might expect from a speedy, productive receiver who's made his mark in the tough SEC. But it's not just the speed that's exciting about Coates, it's the size that goes with it—6-1, 213 pounds. He can get physical when he has to. And he's got the self-assured, 'throw-me-the-ball' approach you want an NFL receiver to possess. Coates has work to do on securing the catch, but if he gets behind the North defensive backs in Saturday's game—watch out. It could get spectacular.

2. QB GARRETT GRAYSON COLORADO STATE (#8 SOUTH)

If Sammie Coates is going to haul in a spectacular deep pass in the Senior Bowl game, it's a good bet Garrett Grayson will be on the other end of that pass. What Grayson lacks in stature (215 pounds) he makes up for in smarts and decisiveness. He had some erratic moments during the practice week in Mobile, and while his arm isn't overpowering, it seems good enough. He's got great touch on throws in the red zone.

Some observers figure Grayson to be a 3rd or 4th round pick. Others say he's clearly a Day Three draft pick (4th-7th rounds). Either way, the Bills have to take a long look at a down-the-line QB prospect like Grayson when they look for rookie competition at the position.

3. CB QUINTEN ROLLINS MIAMI (Ohio) (#22 NORTH)

It shouldn't be difficult to find Quinten Rollins on the field when you watch the Senior Bowl on TV. Look for the distinctive Miami helmets with the red and chrome feather design. And Rollins is worth looking for.

His path to the game is unique—he was a four year starter at point guard for the Miami RedHawks basketball team before switching to football. He's done nothing but play solid, consistent cornerback all week long in Mobile. His point guard skills are evident when it comes to man-press coverage and he usually seems in the right place in zone.

Others to watch:

CB Ladarius Gunter-Miami (#27-South); OT T.J. Clemmings-Pittsburgh (#68-North); OG Laken Tomlinson-Duke (77-North); OL Ali Marpet-Hobart (#50-North); RB Tyler Varga-Yale (#30-North)
