To build the drill and get players to develop the drill in a more dynamic environment the coach can add multiple times when the defender must come to balance.
One area where defenders tend to struggle is transitioning from a full sprint to a position to make a tackle. Many tacklers will continue going as fast as they can as they approach a ball carrier, as a result they are susceptible to any moves the ball carrier tries. In the Burst and Buzz drill players are taught how to accelerate to their maximum chase speed and then come to balance as they approach the ball carrier.
One of the trademarks of any great defense is to have all 11 defenders flying to the ball. This means that as soon as the ball has declared a side, all 11 players need to take off and get to the ball using a path that will keep them in a position to make a play.
