I have Oregon, but if OSU proves they're champions is OK, because this proves the selection was fine, also the need of the playoffs, I see an 8th team playoff coming on in the next year, as some good teams like TCU were left out...glad to see this kind of matchup.
Someone will always be left out. Just the way it goes. I think it is fine as it is at moment this game is already being played at a late date.
