Michigan's offense has one major issue: ineffective Offensive Line play.
So many people in here go on and on about Borges, but the issue is very simple. Michigan's offensive line is NOT controlling the line of scrimmage. Last year, Michigan's OL was good, not great, but good. This year, not so much. People in here are blaming Borges, saying he's calling terrible plays, and saying that Fitz suddenly forgot how to play RB.
Borges isn't calling bad plays, he's calling plays that SHOULD be Michigan's bread and butter. He's calling playing that last year spung Fitz for 1,000 yards. It's hard to run an effective offensive scheme when your OL cannot block your base running play effectively as EVERYTHING you do comes from the ability to block that play effectively the majority of the time. Last season, especially later in the season, the OL was able to effectively block the zone read, and Fitz got off, Denard got off, and everything worked off of that. This year, not so much.
Bottomline, it's near IMPOSSIBLE for an offensive football team to have consistent success with below average OL play.
