Pretty hard to hedge a parlay with 2 of the 4 parts of it open.
The halftime total should be about 17?. You could take the Over there for 2 units. Sets up an 8? pt middle for you on the total, sort of.
The side...well...again, if there is no scoring, I think we'll see Phil -3 or so. You could take that for another 2 units. Gives you another small middle.
If Philly wins by 1-3 and the total lands between 27? and 36 you win the whole shebang whack (+14 units).
If you win both your 2H bets and lose the parlay, you're up 3 units.
If you win the parlay and lose one 2H bet, you're up 9.8 units.
Just what I could come up with off the top of my head but I may have overlooked something.
(edit) to correct: "If Philly wins by 1-3", not "If Carolina wins..."
