if it comes down to Hawaii being your last game and lets say you stand to win 1,500 if Hawaii covers, I'd put 500 on Boise before the game starts- that way you are a winner no matter what. If Hawaii covers, you win the 1,500, but lose 550- net 950...if Boise rolls them, you win the 500 minus whatever you put on the parlay
