The Big Ten Network spent most of Monday in Ann Arbor tracking the Michigan football team and targeting in on a few of the most important topics during fall camp. Topic No. 1, almost every time, was -- of course -- the offensive line. Both head coach Brady Hoke and offensive coordinator Doug Nussmeier continued to praise the group's overall effort and dedication, but stressed that the level of communication and unity continues to be a work in progress. As for senior quarterback Devin Gardner? He says he's been proud of his linemen, not just this week, but all offseason. "They're doing well, they're jelling really nicely and I'm excited to see the improvements they keep making," Gardner said. "When I was in here working (this summer), they were in here working. You can only ask for their best. They came, they worked, they're doing well. "I've only been sacked, like, twice since camp started. And that's a positive." For himself, personally, Gardner continues to stress the importance of keeping his mental focus long enough during games to avoid little mistakes that may ultimately lead to bigger ones -- like turnovers.
