The Dolphins have been held to 17 points or less in their last five games against teams that currently have a winning record (Bengals, Jets, Vikings, 49ers, Chargers), and the Bills are only allowing 13.8 ppg in games played in Buffalo this season (the win over Cleveland was played in Detroit).
Both of these teams are also tied for first allowing just 4.6 yards per play over the last three games;
These teams combined for 40 points the first time they played with the Bills gaining just under 500 yards of total offense. Now adding in the cold weather and possible snow, expect a low-scoring battle. Take the under.
