Let's start with the Big Ten as that should not be to bad of a mess for the selection committee. Ohio State, Michigan, and Wisconsin are all still in the running for a playoff spot. Michigan is in the best spot as if they win out they will get in. Wisconsin has to have some help, but winning the Big Ten Championship could hold alot of weight as they will need to beat either Ohio State or Michigan to get it. Wisconsin is a long shot even if they win the Big Ten Championship in my opinion.
In the SEC it's Alabama to lose as all season they have been the best team in College Football. Even with a loss I could see Alabama getting in. That loss though will need to come in the SEC Championship game. Clemson is another team that is a lock if they win out rest of the season.
Right now I see Alabama, and Clemson as locks to get in which means there is two spots left. If Washington runs the table I see them getting in to the playoffs. Now after that this is where it could get interesting. I think if Ohio State or Michigan runs the table they will be the remaining team in. This means a one loss Louisville could not make it even though there one loss was a close game at Clemson. Oklahoma could be Big 12 champions but with two blowout losses they will not make it.
Now if some of these teams drop a game down the stretch there could be a lot of one loss teams. This means more teams will be in the mix. No matter how you look at it adding more teams is something that will need to be done down the road.
