There isn’t a whole lot you can do, though you have a couple nice tickets. You could take some Jax at 7.25-1 to win it, but I would just hold on to what you have. If the Jags pull off the upset you can hedge some. If the Pats win today, I’d try and wait for a live line hoping they were down at some point and plus money for a hedge. Regardless, I see no way of guaranteeing that you walk away with 3k.
If you need that money, take a look at some Super Bowl MVP long shots before the games start today. I had James White at 125-1 last year and he could have won, but they gave it to Brady (QB’s usually win). I bought Von Miller early in the playoffs the year before and it paid nicely. Have several defensive players for NE and Minn this year that would pay well. Good luck.
