The Bills opened this game at -3 on Sunday night and you can’t find that number anymore. Most books are at -4.5 with a total of 53.5, the highest on the Week 2 board. A line that walks through 3 in 48 hours changes what you are actually betting, and that half point on the wrong side of the field goal is the whole conversation.
Detroit visits Buffalo on Thursday, September 17, 8:15 p.m. ET on Prime Video, for the first regular-season game at the new Highmark Stadium. Both teams are 1-0. Both won games they nearly gave away. Both come in on the same short week, Detroit off an overtime home game and Buffalo off a flight back from Houston.
The line
Buffalo -4.5 (-107 to -108 depending on the book), Detroit +4.5 (-109 to -111). Total 53.5, over -108, under -105. Moneyline Buffalo around -205 to -230, Detroit +170 to +190. BetMGM confirms -4.5 and 53.5 directly.
The opener at most shops was Bills -3 and 52.5. By Monday it was -3.5. By Tuesday it was -4.5 and 53.5. I do not have a handle report, so I am not going to tell you who moved it. I can tell you the market watched Detroit blow a 21-0 lead to New Orleans and decided Buffalo deserved more than a field goal.
At -4.5 and 53.5 the implied score is Buffalo 29, Detroit 24.5. That is what you are being asked to beat.
Week 1, with the excuses stripped out
Buffalo beat Houston 36-31 and looked like the better team while doing it. Josh Allen went 20-of-29 for 334 yards and two touchdowns and ran for two more. Dalton Kincaid caught five for 130. DJ Moore, in his Bills debut, caught five for 100 and a score. The winning drive went 96 yards in seven plays and ended with a 34-yard touchdown to Joshua Palmer with 1:36 left, and Greg Rousseau closed it with his second strip-sack of C.J. Stroud.
Now the part the box score does not shout. Buffalo held the ball for 23 minutes and 43 seconds. It converted 3 of 9 third downs. It ran for 86 yards at 4.1 a carry. Houston had 26 first downs and 381 yards, and the Bills needed a takeaway on the final possession to survive a team that started David Montgomery at running back. Buffalo won on explosive plays, 7.4 yards per snap, not on control.
Detroit beat New Orleans 31-30 in overtime and was outgained 469 to 369. Tyler Shough threw for 410 on 56 attempts. The Lions won the turnover battle 3-1, got two sacks from Aidan Hutchinson and four as a team, and still let a 21-0 third-quarter lead turn into a coin flip. Jahmyr Gibbs ran 29 times for 156 yards and two touchdowns. Jared Goff went 26-of-39 for 206 with two touchdowns and no picks, which is fine and not more than fine. Amon-Ra St. Brown caught 10 for 67 and the overtime winner. Jameson Williams caught four of nine targets and dropped some he should have had.
The 31 includes an overtime touchdown. Detroit scored 24 in regulation. Keep that in mind when you look at a 53.5 total.
Detroit’s secondary, and why the number is 4.5
The Lions are playing without both starting safeties. Kerby Joseph and Brian Branch are on reserve/PUP and cannot come back before Week 5. That is not a Week 1 blip, it is the roster. Kelvin Sheppard’s own offseason review counted 105 explosive plays allowed in 2025, 82 of them through the air, and that was with Joseph and Branch for most of the year.
Then a rookie quarterback making his first start threw for 410 against them. Now they get Allen, who just put 100-yard games on two different receivers in the same afternoon, plus Khalil Shakir, plus a Kincaid matchup that Detroit’s linebackers and replacement safeties are not built to handle.
I would not stretch this into “Detroit allowed 410, so Allen throws for 400.” Shough needed 56 attempts and an overtime period to get there. Allen threw 29 times. But the shape of it is clear: Buffalo will get its chunk plays, and the Lions need the pass rush to finish them before the ball comes out.
Detroit’s offensive line, the actual handicap
This is the part of the injury report that decides the bet.
Starting center Cade Mays is on injured reserve with a broken wrist. Left guard Christian Mahogany, hurt against the Saints, did not practice Monday with a hip injury and Dan Campbell has all but ruled him out for a short week. Rookie first-round right tackle Blake Miller did not practice with a knee and Campbell called it “a concern,” while adding he’d feel better about Miller than Mahogany if he had to pick one. Miller says he expects to play. Backup center Juice Scruggs was limited with a knee of his own.
Monday was a walkthrough, so those are estimates, not practice observations. But the worst case is Ben Bartch at left guard, Larry Borom at right tackle and a limited Scruggs at center against a front Campbell himself called Buffalo’s “catalyst”: Ed Oliver, Rousseau, Deone Walker, Bradley Chubb and rookie T.J. Parker. Rousseau just took the ball away from Stroud twice.
Goff behind a compromised line in a loud building is the scenario the Bills side is built on. If Detroit falls behind by two scores and has to throw, this line covers itself.
The counterargument is Gibbs
Detroit’s answer is to never get into that script. With Montgomery traded and Isiah Pacheco on IR, Gibbs is the offense. Twenty-nine carries in Week 1 was not an accident, it was the plan, and Campbell laughed off the fatigue question on Monday.
Buffalo’s run defense allowed 124 yards at 3.9 a carry to Houston, which is not gashed, but Houston sustained drives all afternoon and kept Allen on the bench for 36 minutes. That is the template. Gibbs on early downs, St. Brown and Sam LaPorta on manageable third downs, keep Buffalo’s offense to nine or ten possessions. Detroit’s third-down defense allowed 47 percent to New Orleans, so the fewer snaps the better.
The problem is that plan runs directly through the guard and tackle spots Detroit might be filling with backups. You cannot separate the two.
Situational stuff
Buffalo picked this opponent for the stadium opener on purpose. OneRepublic at halftime, Bruce Smith honored, hotel rooms downtown reportedly over a grand. The Bills have won four straight home openers by an average of 38.5 points scored, all in the old building. The field was re-sodded after the first surface failed the team’s standards, which is verified, but anyone telling you that means a low-scoring slop game is making it up.
Weather is a non-issue as of Tuesday: high near 75, evening low around 59, slight shower chance, light wind.
Short week is a wash. Detroit played overtime at home and now travels. Buffalo traveled to Houston and back and now hosts on four days’ rest. Nobody has an edge there.
Series: Buffalo leads 8-4-1 in the regular season and has won the last five, including 48-42 at Ford Field in December 2024 and 28-25 in Detroit in 2022. I am not using the 90-point game as a reason to bet the over. Different coordinators on both sides, different stadium, different price.
Buffalo was 12-5 last year and 7-2 at home. Detroit was 9-8 and 4-5 on the road. Bills were 4-5 against the spread at home in 2025. Both teams went over in Week 1. Detroit is 0-1 against the number, Buffalo 1-0 after covering roughly -1.5 in Houston.
Coaching, so nobody gets it wrong
Joe Brady is the Bills’ head coach, promoted after Sean McDermott was let go following the divisional-round overtime loss at Denver. Pete Carmichael is calling the offense and Jim Leonhard runs a defense that has moved toward more man coverage. Detroit has Drew Petzing as its new offensive coordinator after Ben Johnson left for Chicago, with Sheppard back on defense. Two teams with new play-callers on a short week is one more reason not to expect anything exotic. Base stuff wins Thursday.
The pick
I am taking Detroit +4.5, and I would not touch this at +3.5.
The reasoning is not that I think the Lions are the better team. Buffalo is, and Allen against this secondary is the best matchup on the field. The reasoning is that the market has already paid Buffalo for it. The number moved through 3, the key number in this sport, on the strength of one Sunday in which Detroit’s defense collapsed but its offense ran for 165 yards and won the turnover battle 3-1. A 3- or 4-point Bills win, which is exactly where the implied score lands, cashes the Lions ticket.
Buffalo’s defense is not the unit that justifies laying more than a field goal. It gave up 381 yards to Houston and 31 points, went 3-of-9 on its own third downs, and needed a strip-sack to end the game. Gibbs is a better version of what Houston did to it. Hutchinson is a real pass rusher against a Bills line that gave up two sacks, and Allen’s one turnover-free game does not erase his history of giving one away in shootouts.
If Miller and Mahogany are both ruled out on Wednesday, I understand anyone who walks away from this. I would still play it, because the number already reflects the worst-case line and the plus-money on Detroit’s team total over 24.5 tells you the market expects the Lions to score anyway.
On the total I am passing at 53.5. Both offenses can get there, but Detroit’s regulation number was 24, Buffalo held the ball for 23 minutes, and I do not want to lay -108 on a total that has already gone up a point and a half. If you need a play in this market, Gibbs over 19.5 carries at -103 is the cleaner way to bet on the Lions keeping this competitive.
Prediction: Buffalo 30, Detroit 27.
Best bet: Detroit +4.5.
