My thoughts on hedging.
1. Know the current value of your ticket right now.
San fran is +445 in the one book I looked at right now to win the superbowl. If I was to buy your ticket at market value I would buy it for $110 Leaving you a profit of $75 dollars.
So its great to have a +1400 dollar ticket but right now value wise its still not worth anything close to that.
Heres what I would do though and you have several possibilities but I would wait to hedge this until the AFC championship game is over. I absolutely would not hedge if KC wins. Because the problem you are going to run into is the rams are -175 ML. It's going to take an $80ish bet just to get a little bit of profit. But IF the 49ers win your now in your future for $115 and I could see the Chiefs being a -250 ML against the 49ers.
Maybe someone else has a more creative way to hedge but I don't think you can hedge if KC wins.
On the other hand if the bengals win I could see the game being a pick'em. If that's the case I would bet 115ish on the rams ML. Rams win you take home some profit. 49ers win your now in for 150 but if the line is essentially a pick'em you put 200 on the bengals and you are good either way.
Another completely different thing you could do is buy half a point to get the rams to -2.5. Then your probably looking at -125 or something like that. Bet enough to get your initial investment back and Pray the rams don't win by 1 or 2.
