I think the top four are so close the outcome will depend, as often is the case, on the usual unpredictable events. UGA fans are complaining about a reception call on fourth down that probably should have been reviewed, but wasn't. OK, fine, maybe the game hinged on that one play, maybe not. The teams were really close in capability, and I think the same is true for Ohio State and the four in the mix. I see five teams that probably have no more than a 55% chance of winning the next game if they were matched up.
Missouri I think would put up a pretty good fight as well.
