Kevin Byard III, safety for the Chicago Bears, highly commended the innovative up-down drill introduced by defensive coordinator Dennis Allen during the 2025 training camp. This drill, described as a 'rite of passage' by Bears writer Larry Mayer, focuses on enhancing players' stamina and toughness. Byard remarks that the drill evokes memories of high school, emphasizing its significance as a way to 'pay the toll' for a spot on the defense. Allen insists that all players must adhere to this rigorous standard as a prerequisite for becoming part of his defense, a methodology he has implemented since 2009. The up-down drill has been a staple conditioning test utilized across various NFL teams.
