This strategy is actually counterproductive because it limits the easy scoring opportunities that a tired team needs most. Aggressive defense becomes a better offensive strategy when the players are running on empty.

This paper builds a game in which offense adjusts endogenously to the defensive mode. Under two maintained assumptions, three coupled channels (matchup, effort cost, transition) produce a regime structure with closed-form boundaries: man-to-man is the unique equilibrium when teams are fatigued, zone when fresh, and no pure equilibrium survi
