Scenes from the Jayhawk drill

Members of the Kansas football offense and defense square off, one on one, during Les Miles’ Jayhawk drill at Friday morning’s practice.

At least a few minutes during every contact practice are set aside for the drill, during which Miles calls out the names of each participant — one in blue for the offense and one in white for the defense — before each battle.

Miles first introduced the drill to the team in the spring.
