bet for BYU for a few reasons.

1. It would obviously be a big payout.
2. College football is down across the board. I don't think any single team is as dominant as what we've seen in recent years.
3. BYU has a good chance to get a bye in the first round.
4. Vegas has been wrong about BYU all year long. They have a team we beat on the road with significantly better odds.

Anyway, I'm not saying BYU will win the national championship, but I'd put a few hundred bucks on it if I had access to a sports book.
