(update) I ended up keeping the slip as I couldn't find anyone to hedge and the mavs not only covered, but won the game!!!

and I'm 7/8 so far with nba plus a few games tomorrow so I might just end up hitting an even bigger parlay lol
Well congrats if this would win. That is indeed a large bet to hedge it, but I would rather try my luck if I were you as the it seems like it's looking to win. Try your luck, maybe you will win it if not then too bad, but it's a great try. If you consistently hit this much parlay slips you should probably consider creating multiple betslips like this. Think about it, if you divided that betslip in five slips ($10 bet to win $2,800 per slip) you could have sold those and made profits big time, well that's just a crazy idea.
