They are -315ish in game 6. Assuming the same line for game 7 should there be one...
100 parlayed on MIA ML game 6 and then game 7 pays $73.57
100 at MIA series -130 pays $76.92
So yes the price is right/fair.
I happen to KIND OF lean that the Spurs get it done, but I'm not willing to take them on the ML in either game or for the series. I'll probably just take the points in each game.
