I think Alabama and Florida play each other soon. That would mean one of them will lose. I am going to pay attention to Texas and hope they lose at least one game. And I am going to keep hoping, wishing, praying for an Iowa win this Saturday. And then I am going to do that for the remaining 4 Saturdays. I will be at the remaining home games hopefully willing the Hawks on to victory.
Alabama and Florida would play in the SEC Championship, so there's a guaranteed loss between them. Alabama has to play Tennessee and LSU at home, at Mississippi State, Chattanooga at home, and then at Auburn for the Iron Bowl game before talking about the SEC title game. LSU and Auburn are the most "lose-able" in that stretch.
Florida also goes to Mississippi State, has Georgia in the Cocktail Party, hosts Vandy, goes to South Carolina, and then hosts Florida International and Florida State. Anything can happen with these games.
Texas, meanwhile, goes to Missouri and Oklahoma State, hosts Central Florida, goes to Baylor, hosts Kansas and goes to A&M on Thanksgiving night. Plenty of pitfalls in there.
It's not definate that two of those three teams will win out. I do think 'Bama can lose to LSU, Florida might lose to FSU or Georgia (or both), and Texas could lose to Oky State and A&M.
USC could still slide into the BCSNC, but they still have to face Oregon. Boise doesn't have the SoS. Cincy might get in, but Iowa, if they win out, could have the best shot if the big three all lose once or twice.
