Assuming your lines tonite are Cincy -2.5 and total of 46.5<, and your line for MNF is Seattle -7.5, I like the below 3 team 7 point teaser at +150 teaser odds:
Cinn to +4.5 with Over (Cinn-NE) to 39.5< and Seattle Mon nite to -1/2 point or pick, for 3 units (risk 3 units to win 4.5 units at +150 teaser odds)
