Why not? Plenty of CFP and BCS Nat'l Championship games have been blowouts.
My own personal take is that TCU is a great team that got really lucky. They played a weak schedule in the Big 12, other programs such as Bama dropped the ball, Mich and Jim went Full Retards in the semi, and now they go H2H against the current best team.
But I'm perfectly fine if they win this thing.
The last time they won it all, 1938. Last year they went 5-7, this year they play for the Big One.
Last time A&M won it all, 1939. This year's record? 5-7. Hey, one can only hope !
