Attacking a Box & One Defense

"Flash/Back Door"

Bask Door Action

Since the Box & One defense is vulnerable in the middle, by flashing one of the baseline post players into the middle, it creates severe match up problems for the defense. When a good shot is not available on the post flash, High/Low post action is initiated along with back door action by the wing.

Offense Working Knowledge

Like any offense, the key to the success of the "Box & One - Chase" Offense is in its execution and coordination. Players need to be well prepared to execute mid screens, base screens and strong post ups. In addition, players have to think and function as one unit. This requires proper defensive recognition, non-verbal communication, timing and experience.

Game Strategies

Box & One Offense

Scout your opponent if possible. Players need to know what reads to expect during the game. Opponents will generally use only a primary and secondary defense technique in defending screens and post ups. In addition, to their defensive schemes, observer their player match ups. Educate and explain the anticipated defensive reads and their counters. When scouting is not possible, scout your opponent during the game.

Coach not spectator

Be conscience and alert to any defensive changes or adjustments, especially after substitutions and timeouts. Don't hesitate in deploying various alignments and entries during the game so that defenders cannot focus on defending just one set. Move players around and attack the weakest defenders.

Box & One Defense

The most commonly used combination defense is the "Box and One." In this particular defense four defensive players play a box zone guarding areas while one player (the "Chaser") assumes an aggressive, full out pass denial position, and does not allow their opponent to receive a pass or grab a rebound. The chaser's sole responsibility is to deny their opponent the ball.
