that's an interesting question regarding parlaying the money lines. looking at pinnacle odds for NE, Seat and GB, u get the odds for this three team parlay on the ML to be -123 to make 100, so almost the exact same odds as the 10 pt teaser of -120. so, at least in this case, the teaser odds are not a ripoff.
i agree with everybody that arizona is the weakest link of the 3 teams; and good pt re Det being a strong candidate instead cause of Chicago give up. i was considering doing only the 2 tm 6 pt. parlay w GB and NE, but giving -4.5 for each, but that doesn't get me below the -3 that i think is worthwhile to do any kind of parlay for.
