Buffalo Bills vs Miami Dolphins Odds

• Opening point spread: Bills -3
• Opening moneyline: Bills -165/Dolphins +145
• Opening total: Over/Under 48.5 points scored
• Time: 8:20 p.m. ET Sunday (NBC)

UPDATE 7:45 P.M. ET SUNDAY: With kickoff 35 minutes out, DraftKings Sportsbook has the Bills at -2.5 (-125). Last Sunday, the Bills opened -1.5 and quickly advanced to -2.5/-3. Since Thursday, the line has toggled between -3/-2.5 a couple times.

Spread tickets and money are running 2/1 on the road favorite Bills. Further, moneyline tickets and dollars are just shy of 2/1 on Buffalo.

The total opened at 49.5 and peaked at 50.5 multiple times early in the week. By late Thursday night, the number hit its low of 48, and it's been fairly stable since then, save for stretch at 48.5 Saturday/today.

It's now at 48 (Over -115), with the Over landing 67% of bets/54% of money at DraftKings.

UPDATE 6 P.M. ET WEDNESDAY: Buffalo advanced from -2.5 to -3 early in the week in TwinSpires' NFL odds Week 18 market. The Bills are drawing 62% of early spread bets/68% of early spread money.

"The Bills are essentially in a must-win scenario, and the public is backing them. I don’t see any scenario where we don’t need the Dolphins in this spot," Lucas said.

Dolphins QB Tua Tagovailoa (shoulder) is no longer listed as questionable, so he's a go in this huge game for both teams. However, Miami has several questionable starters on both sides of the ball, including Raheem Mostert (knee/ankle) and Jaylen Waddle (ankle).

Tyreek Hill (ankle) is also questionable for Miami. Hill was limited in today's practice before having to abruptly leave because his house was on fire. No one was injured.

TwinSpires opened the total at 50 and is now at 49.5, with 58% of tickets on the Over/59% of money on the Under.

"Sharp play on Under 50," Lucas said.

UPDATE 10 P.M. ET SUNDAY: Buffalo (10-6 SU/6-9-1 ATS) couldn't cover a big Week 17 number, but still notched its fourth straight win. The Bills, laying 14.5 points at home, held off New England 27-21.

Miami (11-5 SU/10-6 ATS) was on a 5-1 SU run entering Week 17, then ran into the Baltimore buzzsaw. The Dolphins trailed 28-13 at halftime, and it got worse from there as they got trucked 56-19 catching 3 points on the road.

In perhaps a modest surprise, The SuperBook opened Bills-Dolphins with Buffalo 2.5-point road chalk. The line moved to -3 within 20 minutes tonight.

"The combination of Miami getting blown out in Baltimore today and the Dolphins' mounting injury list makes this line what it is," Michaelson said. "If this game had been played a month ago, maybe Miami would have been favored, but not now. Buffalo sleepwalks against bad teams and plays well against good teams.

"And the wiseguys would be all over Buffalo at anything south of 3."

The total is on the move early, as well. It opened at 48.5 on The SuperBook's NFL Week 18 odds board and quickly advanced to 49/49.5/50.
