If you only have room for one piece of CFB line movement today, make it Air Force. Starting quarterback Liam Szarka is out for the rest of the season with a lower leg injury suffered in Saturday's win over Navy, and the Falcons do not run the kind of offense where you slide the next guy in and the math holds. That is a number with real consequences attached, and it is the one I would have respected first.

The rest of the Monday wire is personnel news with a longer fuse. Real, but slower.

CFB line movement today: why the Air Force quarterback injury matters most

At most programs, a quarterback injury is a passing-efficiency problem. At Air Force it is a possession problem. The quarterback is the hinge of the entire ground attack, the read on every option play, and by extension the engine of how long the Falcons keep the ball away from you. Lose him and you do not just lose throws, you lose drives. Shorter drives mean more possessions for the other side, and more possessions is the quiet thing that bends a total upward even when nobody's offense gets better.

So the honest read runs both directions. The side should move against Air Force, and I would expect it to. The total is the messier conversation, and messy is usually where the soft line lives. I don't have the updated Falcons depth chart in front of me yet, which is exactly why I am not pretending to know the size of the move. What would confirm it: the name of the replacement and whether he is a runner in the same mold or a stopgap the staff has to build a different call sheet around.

checked the almanac: service academy football has been quarterback-shaped since long before any of us had an app on our phone, and the Commander-in-Chief's Trophy, contested among Army, Navy and Air Force since 1972, has a long habit of turning on which academy still has its quarterback upright in November. back to business.

Tennessee quarterback decision vs Arkansas

The No. 15 Vols still have not named a starter, and the head coach spent Monday walking through how he is making the choice rather than announcing it. Over on the other sideline, Arkansas head coach Ryan Silverfield was talking about execution, which is coach-speak for we know exactly how thin our margin is.

An unnamed quarterback is a market condition, not just a storyline. Books price uncertainty conservatively and bettors hate committing into it, so the number tends to sit still and the total tends to sit lower than the matchup deserves. When the name comes down, that is when the honest price shows up. That's a tell worth waiting on rather than guessing at.

Ole Miss, Notre Dame and the rest of the injury board

Ole Miss expects star running back Kewan Lacy back for the trip to Vanderbilt, per the head coach on Monday. A returning featured back is the cleanest positive signal on this board, because it restores short-yardage conversion and red-zone trust at the same time, which is a side and a total story in one.

Notre Dame is the opposite direction. All-American cornerback Leonard Moore is in concussion protocol and listed as questionable, with linebacker Kyngstonn Viliamu-Asa also questionable. Protocol is a late-week story by nature, so anything written about it on a Monday is a guess wearing a tie. Losing a corner of that caliber is a passing-game and scoring-environment question, not a cosmetic one.

What ESPN's College Football Playoff projections actually tell you

Week 5 is in the books and the projection cycle churned again, with Florida sliding in the seeding after the road loss at Missouri while still holding a top 10 spot. These are projections, not the committee, and the committee has not met. What they are good for is a sentiment reading: they tell you where perception is drifting, and perception is most of what prices playoff and conference futures in the weeks between games. A team that keeps its top 10 standing after a brutal road loss is a team the market is still giving the benefit of the doubt. That benefit is a price, and prices built on benefit of the doubt are the ones I check my own number against hardest.

Nothing here is a play yet. The Air Force situation is the one I am actually working, and I want the replacement's name before I touch it.

What I'm watching next: who takes the first snap for the Falcons, when Tennessee names its quarterback, and whether Leonard Moore clears protocol late in the week. Three names, three numbers.
