Indianapolis vs. Buffalo
Don't look for the Colts to improve their 7-0 road record. The Bills' 5-1 "under" mark since promoting Perry Fewell and the January conditions at Orchard Park makes this look like a possible low-scoring affair.
New England vs. Houston
New England is only 1-5 vs. the spread as a visitor this year, while Houston historically closes fast at home for Gary Kubiak (7-0 vs. line in last 2 reg.-season games as host since '06).
Pittsburgh vs. Miami
The Dolphins' are 6-1 vs. the "over" at home this year.
