Houston's pass defense clamps down on receivers, and Allen's neutral script limits explosive plays. Allen averages 5.2 yards per carry on the ground and 0.0 targets per game through the air—he's not a high-volume passer in this offense, and facing a Texans secondary that suppresses receiving production, he'll stay contained well short of 253 combined yards.

Allen's legs are a consistent weapon against Houston's soft run defense. He's averaging 5.2 yards per carry and Houston gives up more than average on the ground, creating space for him to hit a 12-yard scramble or designed run in a neutral game script where Buffalo won't be forced into pure passing mode. One explosive run is all this needs.
