Iowa State at BYU. Lean: Iowa State +10.5. No call on the total.

Spread.Market first: BYU’s move from a DraftKings opener of minus 14.5 to the captured minus 10.5 is best explained by the Monday news that star RB LJ Martin and LB Isaiah Glasker are doubtful, not by an overlooked generic underdog angle. That adjustment is meaningful, but Iowa State remains live inside double digits after Aiden Flora and its offense produced 45 points and 577 yards against West Virginia. Martin’s absence removes BYU’s primary early down threat, while Glasker’s potential absence matters against a Cyclones rushing attack that just generated 265 yards. Iowa State plus 10.5 is a lean, not a bet, because the injury news has already driven a four point move and BYU’s defense held TCU to 10.

Total.Market first: the total fell from the captured DraftKings opener of 50.5 to 46.5, plausibly reflecting BYU’s 17-10 game at TCU, Martin’s doubtful status and substantial under support. That explanation is credible, so the case is only an over lean. At 46.5, the number may have overcorrected for one absent runner: Iowa State just scored 45 while producing 577 yards against West Virginia, and Glasker’s doubtful designation weakens BYU’s second level. Forecast conditions are not a clear scoring obstacle. The internal total of 50.77 supports the direction but is not decisive because its documented error is larger than this gap and it does not incorporate injuries or pace. The lean does not survive a lower total.

Where our number looks wrong.The model likely overstates BYU because it learns only final margins from four games and does not price Martin or Glasker. Its flat home field treatment also cannot distinguish this specific late Friday home spot.

• Iowa State beat West Virginia 45-42 on October 3, with 577 total yards and 265 rushing yards.
• BYU’s Martin and Glasker were described as doubtful for Iowa State on October 6 reporting.
• DraftKings Network listed Iowa State at BYU at 46.5 and reported listed betting splits for the total.

Spread.Market first: BYU is a 4-0, eighth-ranked home team with a defense allowing 14.3 points a game, Iowa State is 3-2 under a first-year coach and just gave up 518 yards to West Virginia, so a double-digit home number is easy to explain. The interesting part is the path: DraftKings hung BYU -14.5 on 9/30 and the market now sits at 10 to 10.5 everywhere. That move lines up with the news: LJ Martin (ankle) and LB Isaiah Glasker both left the TCU game and Kalani Sitake called both doubtful on 10/5. Without Martin, BYU's offense in the TCU win was Bear Bachmeier running, with 62 passing yards and 294 total yards. BYU's pass offense ranks 114th, so laying 10.5 asks a one-dimensional attack to win by margin. Iowa State brings a real ground game (Aiden Flora 212 rushing yards vs WVU) that can shorten the game. Our -13 does not see the Martin and Glasker absences, which explains most of the gap. I lean Iowa State at +10.5, not +10, but the market has already moved most of the way, so it stays a lean.

Total.Under case: BYU without LJ Martin leans on Bachmeier runs and a weak passing game, Iowa State wants to run behind Flora, and both styles drain the clock; BYU's defense allows 14.3 a game. Over case: Iowa State has scored 33.6 a game and just traded 87 points with West Virginia, its defense is leaking yards and now loses safety Drew Surges, BYU averages 37.3, and the TCU game was played in heavy rain while Provo looks dry with light wind. Our 50.8 is mostly last year's offenses and sees none of the injury news. These cancel out near the current number.

Where our number looks wrong.Our -13 is built on final margins and the preseason prior and cannot see that BYU will likely play without its lead back LJ Martin and top linebacker Isaiah Glasker. Most of the 2.7 point gap to the market is that injury news, and the market is right to have moved off the lookahead number.

• Jimmy Rogers: safety Drew Surges (arm) will be out against BYU
• BYU passing offense 114th at 179.8 yards a game; Iowa State rushing 197.4 yards a game; preview line BYU -11, total 48.5
• BYU 294 total yards in a rainy 17-10 win at TCU
• Iowa State allowed 518 yards and scored 45 vs West Virginia
• LJ Martin doubtful for Iowa State

Spread.The market makes BYU about a ten and a half point home favorite, and the strongest explanation is simple: BYU is 4-0 and ranked 8th, holds a top defense at 14.3 points allowed per game, and plays at home on a Friday night, while Iowa State is a first-year-coach team with almost no returning production that was beaten by Utah and gave up 42 to West Virginia. That explains the number without any help. What the price may overstate is the gap: BYU's two Power conference wins this year came by 11 over Arizona and 7 at TCU, and the running back room is thin with L. Martin out. Iowa State scored 45 and 55 in two of its wins.

Total.The total has fallen from 47.5 to 50.5 openers down to 46.5 at most books, a steady move that the market has already absorbed. The over case: Iowa State scored 55 and 45 in two games and gave up 42 to West Virginia, and BYU can score. The under case: BYU's defense has held opponents to 7, 17, 23 and 10, BYU's games have run 45, 64 and 27 total points, and the favorite tends to play with a lead and run the clock at home. Weather is mild with light wind per the captured forecast, so it does not push either way. I found no verified news that separates the two sides, so the direction is a coin flip around the number and I would not take a position at a captured price.
