What it is

Bills CB coach Jay Valai teaches five cornerback drills covering press technique, ball disruption, and red zone coverage for intermediate to advanced defensive backs.

Why it's great

Valai breaks down the hook-and-swat timing that most coaches skip — when to trigger off the receiver's head turn versus route shape. The bait-and-bail and back shoulder drills address game situations that highlight reels show but instructional videos rarely teach in sequence.

How to use it in practice

Run as station work: press/transition into hook & swat for timing, then bait & bail for route recognition. The chest-to-chest drill isolates back shoulder position without a ball first, then adds the catch point. Finish with ball/me/man red zone coverage to apply all concepts in tight windows.
