Every defense looks tired in the fourth quarter. The question is whether it looks tired because of the opponent or because of the plan.

Where the snaps go

Count the snaps up front and a pattern shows up quickly. The first unit plays most of the meaningful downs, and the rotation shrinks as the game tightens.

That is a defensible choice in a one-score game. It is harder to defend when the same pattern repeats week after week and the late-game tackling slips with it.

What to watch next

  • How many linemen see the field before halftime
  • Whether the second unit gets a full series in the third quarter
  • Missed tackles after the first contact in the fourth

None of this requires a new scheme. It requires a little more trust, a little earlier.
