New York Jets at Chicago Bears. Lean: Chicago Bears -3.5. Lean: Under 43.

Spread.Chicago -3.5 is best explained by the market discounting a Bears offense without a confirmed starter, after the look ahead price fell sharply from -8.5 and the Jets showed real passing life with Geno Smith. That is a rational adjustment, not a signal to trust the internal -11. Still, the current price may underrate the Jets' new Week 4 absences: Breece Hall, Adonai Mitchell, Dylan Parham and Mason Taylor did not practice Wednesday. Chicago also just handled Philadelphia 27-7 behind Case Keenum, who was decisive and turnover free. The Bears retain a capable home defense and the Jets lose a major part of their run game and offensive depth. I lean Chicago -3.5 at -102, but the unnamed Bears quarterback and potential return of safety Minkah Fitzpatrick keep this below a bet.

Total.The total's strongest market explanation is clear: it fell from the 45.5 look ahead to the 42.5 to 43.5 range after Williams' hamstring injury, Chicago's unresolved starter, and the Jets losing Hall plus several offensive contributors. That move deserves respect, and the internal 46.33 forecast has no documented market edge and a historical high bias. The remaining case for Over 43 at -107 is situational and modest. Soldier Field projects dry, 65 degrees, with 5 mph wind, so there is no weather case for the reduced total. Keenum's first start still produced 27 Chicago points, while Smith generated 24 against Detroit with 321 passing yards and three touchdowns.

Where our number looks wrong.The internal -11 overstates Chicago because it still carries a Caleb Williams projection and preseason weighted Jets baseline. It does not adequately reflect Williams' hamstring absence, the unsettled backup decision, or Smith's strong opening three games.

• Smith completed 31 of 37 passes for 321 yards and three touchdowns in Week 3 at Detroit.
• The Bears have not named a Week 4 starter; Caleb Williams remains sidelined from walkthrough activity with a hamstring injury.
• The Jets listed Hall, Mitchell, Parham and Taylor as nonparticipants on Wednesday.
• The stadium forecast calls for 65 degrees, 5 mph wind, dry conditions and 1% rain chance at kickoff.
• Smith recorded 321 passing yards and three touchdowns against Detroit in Week 3.

Spread.Market first: Chicago -3.5 is a backup quarterback number. The look-ahead sat near Bears -2.5 before Monday night, and the Bears moved through the key number of 3 after Case Keenum led a 27-7 win over Philadelphia with six takeaways. Caleb Williams (hamstring, reported 3 to 4 week timeline) did not practice Wednesday and Ben Johnson has not named Keenum or Tyson Bagent. Our number of Bears -11 is not usable here: it still carries Williams as the projected quarterback. What keeps me on Chicago is the other locker room. The Jets ruled Breece Hall out week to week with a quad injury and also list LG Dylan Parham, WR Adonai Mitchell, TE Mason Taylor and LB Kiko Mauigoa as week to week, so Geno Smith, who has thrown well, faces a top pressure defense without his lead back, a starting guard and two pass catchers. The Jets defense ranks near the bottom in EPA allowed. That is a lean, not a bet, because the move from 2.5 to 3.5 already charged for Monday night and takeaway spikes do not repeat reliably.

Total.The market sits at 43 after drifting down from a 45.5 open at DraftKings. Our model says 46.3, but after its known 1.2 point high bias it is near 45, and it does not see either key injury. Chicago has a backup quarterback and has allowed 9 and 7 points in its last two games; the Jets lose Breece Hall, a starting guard and two pass catchers. The over case is real: Keenum moved the ball in Ben Johnson's system, the Jets defense grades poorly, Geno Smith just threw for 320 yards, and the weather is mild with light wind. I side under as a lean because both offenses are missing their best pieces and the Bears defense is generating pressure and turnovers, but 43 is a fair number and not a bet.

Where our number looks wrong.Our Bears -11 is inflated twice over: the rating treats Caleb Williams as the starter when he is out and a 38 year old Keenum or Bagent will play, and the calibration map stretches the raw 8.6 margin. It also still anchors on the Jets' 3-14 2025 season while Geno Smith has been efficient. A fair number with the backup is closer to Bears 3 to 4, which is where the market sits.

• Bears beat Eagles 27-7 with Keenum starting
• Under 2 of 3 for both teams; Bears allowed 9 and 7 points in recent weeks; total 42.5
• Hall expected to miss Sunday with four more Jets week to week

Spread.Strongest explanation for Bears -3.5: Chicago is at home, the Jets are 1-2, and Case Keenum played a strong Monday night game on short notice, which pushed the number from an opening Bears -2.5 to -3.5. Caleb Williams (Grade 2 hamstring, reported 3 to 4 week timeline) is out, so Chicago is playing a 36 year old backup, and the market has already priced the Williams absence. What it may have over-adjusted to is one good Keenum game. The Jets have Geno Smith, but depth concerns: Breece Hall is questionable with a thigh injury, Dylan Parham left Week 3, and several defensive and TE/WR pieces are out or limited. The edge is small: a one game move on a backup QB with unresolved availability on both sides.

Total.The total sits at 42.5 to 43.5 with no move of note. Arguments for the under: a backup Bears quarterback, a Jets offense that was poor last year, and possible Jets skill and line absences. Arguments for the over: Keenum's Monday game showed the Bears offense can score with him, Jets defense gave up a lot to Detroit, and the forecast is mild with gusts below 20 mph, so weather gives no edge. Generic under narratives without new evidence are not enough, and the two cases roughly offset. There is no clear incremental information against the market number.

• Total 43.5, gusts below 20 mph forecast
• Total 42.5, analyst leans under projecting 20 to 17
