Bills vs. Dolphins 2013 odds and lines: Miami favored at home

The Miami Dolphins host the Buffalo Bills in Week 7, and are comfortable favorites in the early going. According to Oddsshark, the Dolphins are favored by eight points in Vegas. The line opened at minus-11.5 points in Miami's favor, but has gone down since then.

Miami is coming off a bye week hoping to right the ship after two straight losses. They went down to the Baltimore Ravens in Week 5, 26-23, failing to cover as 2.5-point favorites. The Dolphins are 3-2 on the season and 3-2 against the spread. By far the biggest concern is the porous offensive line, which threatens to derail an otherwise promising season. Ryan Tannehill is on pace to get sacked 77 times, which would break an NFL record.

The Bills are just wondering who will play quarterback at this point. Third-stringer Thaddeus Lewis injured his foot in last week's 27-24 loss, and the team signed Matt Flynn as insurance. The Bills fell to 2-4 in the standings, but have been a favorable bet for gamblers, going 4-2 against the spread. They were able to beat the 5.5-point spread against the Cincinnati Bengals by taking them to overtime.
