It's mind boggling how simple the math is and how many people mess this up. Your question can not be answered because you'd state the teaser odds you're getting and you also say the the moneyline is -265 but where is it -265 and what is the underdog line?
Okay so @ Pinnacle I'm seeing -265 / +235
So risk/return = implied probability.
@-265 Risk $2.65 returns $3.65 ($2.65 stake +$1.00 win). 2.65/3.65=72.6%
@+235 Risk $1.00 returns $3.35 ($1.00 stake +$2.35 win) 1.00/3.35=29.85%
72.6%+29.85%=102.45%
To remove vig divide by by 102.45
72.6/102.45=70.86%
29.85/102.45=29.14%
So no-vig probabilities are: Packers 70.86% / Lions 29.14%
Save the math and plug it in here:

The no vig moneyline is -243.2 / +243.2
Calculating teaser odds. You just need to convert it from a single bet into parlay terms.
2 team +100 you need to win 50% to break even so take square root of .50 = 70.71% plug into
odds converter = -241.4
2 team -110 you need to win 52.38% of the time so take square root of .5238 = 72.374 plug into odds converter -262
So your question depends on how much do trust Pinnacle's #'s right now. If someone offering -6 will take your bet at 2-team +100 you're getting -241.4 while the no vig Pinnacle line is -243.2. That's an extremely small edge normally not ever worth pushing based on rough data like this - However - IF you find another leg with a larger edge to match it with then sure its a great play so long as we're still talking 2-team +100
Please enlighten me here. What if the total was 36 you still would rather not? LT was generous with his comment - you have to be very selectively with these though.
