QBs are that important. Just look at how bad the Patriots and Colts were when Tom Brady and Peyton Manning went down.
Remember this is not Ohio State can't make the playoff without Miller, they are making the debate that the B1G should be eliminated entirely.
It's silly. Any P5 team that runs the table will get in for one thing. A 1 loss B1G champion still has a good shot at getting in depending on the landscape. Especially if they played a legit non-con.
