Anytime the line is close, I see it as a win/win. It just requires you to bet against BYU.
If they are a slight favorite, I take the other team. Then if they win, I loose my money, but who cares, I’m happy.
If they are underdogs, bet the other team. If they lose, at least I get a payout.
You just don’t want to lose the bet, and the game.
