I agree wholeheartedly with the OP's analysis. I watched that game and OSU could not figure out how to stop the Michigan running game. Much of that success was predicated on Michigan using 2 TE's. But the interesting part to watch was that whenever OSU tried to load up against the run, Gattis had the perfect pass play dialed up. Once Gattis found an advantage, he was able to control the game and keep OSU's defense off balance all game.
The question for us will be whether UM has an advantage in either the passing or running game that allows Gattis to dictate the game. I would argue going in that we have a passing game advantage over most defenses on our schedule that is similar to the running game advantage Michigan had, which will allow Gattis to dissect whatever a defense tries to do.
