The Michigan coaching philosophies are setup based on Forcier, so they'll use him the way they used Forcier. Forcier is a much better passer than Robinson, but Robinson is a much better runner. You're going to see a lot more triple option with Robinson.
The trouble is, I'm not entirely sure Michigan's triple option is even in the game. I'll have to look at the playbooks, but I don't think it's there at all. The play has been around since Urban Meyer was at Utah at least, but no team has used it as extensively as Michigan this season.
