INDIANAPOLIS -- Graham Glasgow had Alex Mack homework this summer.

When Jim Harbaugh and his new staff arrived at Michigan last year, offensive line coach Tim Drevno assigned an NFL player to each Wolverine lineman.

Study this guy. Between spring ball and fall camp, this is how you'll learn to play like an NFL lineman, as the Harbaugh staffers tried, in many ways, to create an NFL atmosphere.

Glasgow, Michigan's 6-foot-6 and 307-pound center, got Mack, the Browns' 6-4 and 311-pound veteran Pro Bowler.

What did he think?

"He runs the outside zone so unbelievably well," Glasgow said Wednesday at the combine. "I tried to look at that. His footwork, the way he can run off the ball and not get too deep and be able to push defenders back at the point of attack. Looking at his hand work in his pass pro, things like that are just awesome."

Mack was a first-round pick in 2009. Glasgow doesn't project that high, but he did help himself with a strong performance at the East-West Shrine Game that led to a late invite to the Senior Bowl. Now he might have a shot at going in the middle rounds.

Mack had a part in that. Glasgow said he watched about half of Mack's 2014 games last summer while preparing for his final year at Michigan, which would be by far the best season of his career.

Improving his diet had something to do with that. Following a 2014 DUI arrest, Glasgow said he cut beer, among other things, out of his regular meal plan. He's been answering questions about that DUI charge from NFL teams here at the combine.

Taller than most centers at 6-6, he's viewed as pretty athletic with a good first step. If he can be anything like Mack, he'll take it.

"There's a lot of things he did that I tried to do this season," Glasgow said. "I think that really helped me a lot."
