MOBILE, Al. -- The measurements for the Senior Bowl took place on Monday morning, and there's nothing quite like beginning evaluations with at least 500 NFL talent scouts in a hotel ball room while 106 college football players walk on stage, no shirt, no socks, just spandex shorts.

That was the scenario for Jake Locker and Mason Foster, both of whom are playing for the North team.

Locker measured 6 feet 2 and two-eighths (better known as one-quarter inch) and 228 pounds.

His hand: 9 and seven-eighths. Arm: 32 inches. Wingspan: 76 and one-eighth.

Foster was 6 feet 1 and one-eighth, 241 pounds. Hand: 9 and three-quarters. Arm: 31. Wingspan: 74 and five-eighths.

Ran into Tim Lappano, Locker's first offensive coordinator at the University of Washington was at the Senior Bowl as he's part of the Detroit Lions coaching staff. As much as anyone, he knows both how far Locker has come and what will be evaluated this week, and I found his assessment of Locker quite insightful.

Lappano: "Well, he came from a Wing T, running-style offense and some out of the shotgun, but when we recruited him, I knew that he had to have the spread-option.

"He was a spread-option quarterback. I put in some pro-style, West Coast offense that I had done with (Dennis) Erickson at a couple of different places, and everything that you had to teach him in the passing game -- his footwork, his release - everything was pretty new to him, and I thought that he struggled a little bit throwing the deep ball. I think he was a lot more accurate with the intermediate, quick passes. It was unfortunate that he got injured because he was rolling. He was doing well.

"And I think that he still has to learn, I think, to go through progressions and make smart decisions with the football. He's got a ton of arm strength, he's got a quick release. He's got a strong arm. I just think that he needs to make sure that he identifies coverages, and it goes from Progression One, Two to Three without making mistakes, forcing the football.

"I watched a little bit of him this year when I could on Saturdays, and I saw him force the ball in there a little bit. His athleticism, you can't argue with. He's as good a competitor as I've ever coached. I've been doing this 30 years, and he's as good a competitor as I've been around. I think if he can just make good, smart decisions with the football, he will do well.

"He will do well in this game. This game is all Cover One and Cover Three. There's not blitzing in this game, and he should eat that up and make good decisions. I think he'll do really well. I think this is really an important evaluation for him, this game, and I think the combine will be the second stage where he's going to have to step up and throw the ball with accuracy.

"Everybody knows his athleticism, his running ability, his ability to scramble the football. But just throw the ball, make good decisions, throw it accurately, and he can still go very high."
