really trying to narrow down this NFL teaser, will award points for help

[priskilla22]

I'm trying to narrow this down to 4. Here are my 6 options I've gotten down to.

Atlanta +10
Lions +9
Bengals +6
Bengals/Colts Under 53.5
Packers -2.5
Steelers -0.5

What do you guys think? Any of these plays you think I should avoid?
