A Backdoor Cut in basketball is an offensive move in basketball. It is considered one of the most basic and primary basketball cuts used in a number of offensive strategies.
In a Backdoor Cut, a player who is on the perimeter steps away from the basket and takes the defensive player with him. During this move, the offensive player suddenly cuts behind the defensive player for a pass. The opposite of this term is the V cut.
The backdoor cut is effective at reducing defensive pressure on the wing and creating scoring opportunities when the initial passing option is blocked by an aggressive defender.
