Well, there are some things Brown can do that make the offense better as a whole. But when you need to pass, Rowe is the better option. Rowe made some bad throws today too, but he at least gives the receivers a chance. Brown is at his best in the option game. If that isn't a weapon, then there is not reason to have him in the game.
Ohio State was just too big for MD. Both the Offensive and Defensive lines just pushed MD around all day.
