He is not Jairus Byrd good, but Bush is certainly good in pass coverage. He turns his hips when he reads which receiver the quarterback will target and has good closing speed to break up the pass.
He can get fooled by good quarterbacks and double moves by wide receivers. He does have a tendency to bite on plays which could be disastrous when you are playing the ball as deep as the free safety.
