Seeking help with estimated Clev @ Det game seven line....

[JPT III]

Can someone estimate, with a reasonable degree of certainty, what the MONEYLINE in the potential game 7 between Cleveland and Detroit would be? I checked scoresandodds.com (which I'm not sure is reliable) for the line in the other 3 games at Detroit, but the lines seemed a bit all over the place. I really need to hedge out a VERY LARGE, VERY +EV position I have on Cleveland to win the series. Depending on what I would be able to get on the Detroid moneyline in game 7, it appears that the optimal course of action is to make myself a little homemade parlay, by placing money on Detroit tonight (to win) and again on Detroit to win game 7 (rather than taking the available Detroit +184 [MB] to win the series).

Any input will be greatly appreciated. THanks in advance.
