WV would need a lot of help to get in, but there's still a ton of football yet to be played. Right now, one would have to believe the Pac 12 and Big 12 are currently on the outside looking in. If Oklahoma wins the Big 12, then I don't believe anyone from that conference will get in. WV is probably the only team in that conference that has a chance of getting in. I do think WV beats Oklahoma though, so they have a shot at going 11-1, but without a lot of help, it will be tough to leap frog a bunch of teams.
Alabama will get in, assuming they don't free fall against Auburn and the SEC title game.
Ohio State is in the cat bird's seat as well, as they simply need to beat MSU on the road, and Michigan at home. OSU might even get in, despite not winning the Big 10 East, as PSU holds the tie-breaker currently. Michigan will obviously get in if they win out, including winning the conference title game. Michigan losing to Iowa pretty much closed the door on the Big 10 getting two teams into the final four.
Clemson and/or Louisville will get in, assuming they win out. Potentially, both of them could get in.
Currently, I see those (5) teams as the contenders for the 4 spots. With that said, there's still a lot of games yet to be played. Anything can happen, and usually does.
