It depends on the path - so unless you’ve got a bracket and are 95% sure who plays who the rest of the way, take the futures bet.
EDITING TO REVISE - at +350? No way.
what i mean is if buff plays kc next then philly, you might be better off ML x 3. Actually FACT - you will.
but say they play jax (just a possbility) then the giants, the +550 is better
the way i read futures is its pricing in the most likely matchups. And +550 tells me they’ll be underdogs (esp with a -5.5 this weekend) at LEAST in 1 more game, probably two. Personally i dont think they beat kc, philly, maybe not even dal or sf if they get to the sb. I wouldnt take the future, i’d try each game by game
