What to watch in this week's Senior Bowl

We've got plenty of folks on the ground in Mobile, Ala., at this week's Senior Bowl practices and Saturday's games, and we'll offer updates as the week goes along.

Until then, our analyst Todd McShay fills you in on a few players to watch this weekInsider.

Here's the full roster of who's playing, though Baylor's Kendall Wright and Oklahoma State's Levy Adcock will be sitting out. Texas A&M DE Tony Jerod-Eddie was a late addition to the roster.

Oklahoma State's Brandon WeedenInsider

(Grade: 79): He has a quick release and strong arm, but Weeden's accuracy and decision-making were spotty in 2011. He got away with a lot of questionable throws and decisions due to the Cowboys' wide-open offense and the ability of WR Justin BlackmonInsider to bail him out. How will Weeden perform on a level playing field compared to other top prospects?

McShay says one big Big 12 player is under the radar.

Iowa State OT/G Kelechi Osemele (84): Osemele lined up at left tackle in college and should get some reps there this week, but don't be surprised if he struggles to protect the edge. He doesn't show great lateral quickness on film. On the other hand, Osemele has the tenacity, size and power to turn heads when he slides inside to guard, and that's where he might fit best in the NFL.

Osemele weighed in at 333 pounds, the third-heaviest player in Mobile this week. His 35 1/4-inch arms were the longest of any player at the Senior Bowl. Jerod-Eddie was fifth with 34 3/8-inch arms. Osemele's wingspan was predictably the longest as well, at 85 1/2 inches.
