Five storylines: Iowa at Michigan 

November, 15, 2012
ANN ARBOR, Mich. -- Each Thursday, WolverineNation will take a look at five storylines heading into Saturday's game. These are five to look at as the Wolverines take the field at Michigan Stadium for the last time during the 2012-13 season.

1. Will Denard or Devin take the most snaps?
Yes, it's Robinson's senior day, but does that mean he'll play? On Monday, Michigan coach Brady Hoke said it all comes down to his health, and at this point Robinson remains day-to-day. What makes this more interesting is that it also might hold implications for next Saturday against Ohio State. Hoke has made it clear that he doesn't believe in playing someone in games who doesn't practice. And while we don't know to what extent Robinson is practicing, it begs the question: If Robinson sits out for three consecutive games, would he really be ready to play in The Game.
