140 to win 9100 is an auto-hedge.
Put $280 on the Colts. If they win you profit $140. If they lose you are down $308.
The next week if they are still win you put $700 the other side. If they lose you now profit $252. If they lose you are in the hole $1,078.
Conference Championship you fade them again for $1500 this time. If they lose you profit $402. If they win you are in the hole $2,728.
Super Bowl you fade them for $4000. If they lose you profit $1,272. If they win you profit $1,918.
Don't see why you would be greedy and not take double your money worst case.
