It would be nice if things work out well for us to have a win on the road against Minnesota, Then beat a #20ish Wisconsin (after their UCLA win), then go on the road and beat a #17ish NW (assuming they win their next 3 games which would include @ Oregon). If all that happens, and Nebraska is somehow able to run the table outside of Ohio State, they'd probably be ranked low #20's when we meet, and I think we could possibly be afforded a loss to them at home, albeit a close game, and still make the playoffs.
Beat Nebraska and the above scenario plays out, we would be ranked 8th or higher.
But if our only losses are against a 1-loss Ohio State and a 2-loss Nebraska, I think we'd be in the top 12.
Indiana, Ohio State, Iowa, and possibly USC in the playoffs.
