Basically, you have to hope the lakers don't win, but that isnt going to happen, but if you do want to break even and freeroll a bit and then have a possible hedge, here is what i would do.
I'm basing all this on a $1,000 unit because its easier to see, you can adjust the unit size to whatever fits your roll.
Right now you have minny at 29-1
option 1: (already have)$1,000/$29,000 minny wins it all
option 2: bet $1,000/$9,000 pacers win it all
option 3: bet $1,000/$7740 pistions win it all
option 4: bet $7,350/$3000 lakers win it all
make the above bets and are current lines from pinny.
here are your scenarios:
1. Lakers win, break dead even (most likely), but you do recover the money back from your original t-wolves bet.
2. Minny wins, celebrate like mad, you win $19, 650
3. Pistons win, you lose $1610, but you can hedge if they make it to the finals.
4. Pacers win, you lose $350, but again can re-hedge in the final.
I guess it depends on how important the money is. There is no way to lock up guaranteed money on this bet. If the money isn't that important I would let it ride and hope minny can win one game in LA, and then the lakers price will go down a bit.
