It's a bit tough to choose any of these four underdogs because they're all playing on the road. Baylor and FSU are heavy favorites over Texas and Miami and, in all honesty, would have to play one of their worst games of the season to lose.
The other two games are closer calls, but I just can't see UCLA winning at Maples. Stanford is playing very well right now, and UCLA hasn't been great on the road.
So I'm going with Louisville over Notre Dame as the only surprise out of the four. ND has been better at home than on the road, but looked vulnerable in a recent home win over Virginia. Louisville gave Florida State just about all they could handle in Tallahassee.
If Hines-Allen can't play tonight, though, it's hard to see Louisville winning.
