Can I play the sometimes the letdown team wins game? I'm just winging this from memory of old pre-game 'letdown' fodder.
1986 Oklahoma 42-8 over Arkansas in Orange (lost to Miami and was a spectator to PSU v Miami)
1996 Nebraska 41-21 over VaTech in Orange (crushing defeat to UT in first XII CCG, cost chance at 3 MNCs in a row)
1999 Nebraska 31-21 over Tenn in Fiesta (one loss, ahead of #2 VT in some metrics, not in BCS title game)
2000 Nebraska 66-17 over NW in Alamo (close one point loss at KSU bumped them out of XII CCG and down to Alamo)
1988 Miami 23-3 over N in Orange (ND beat WVA in Fiesta for title, Miami 'wuz robbed at ND'.
1990 Miami 46-3 over Texas in Cotton (we all like bringing up this one, Randall Hill running with cheetahs)
2000 Miami 37-20 over Florida in Sugar (no explanation needed, they beat FSU, FSU got nod to score 2 pts vs OU)
2008 Texas 24-21 over Ohio St. in Fiesta (OU loses to UT, UT lost to TT, OU finished ahead of UT, goes to BCS title)
2010 Alabama 49-7 over MSU in Citrus (Fla beat Bama in CCG)
we get it, I get it, let downs happen, but there's as much evidence to present to demonstrate that it can be managed.
