Go Under
The cutter's defender goes under the screen between the screener and basket, conceding the perimeter shot but staying between the cutter and the rim.
About This Action
The 'Go Under' coverage is a fundamental defensive technique employed against off-ball screens or pick-and-rolls, primarily when guarding a non-shooting offensive player. It involves the defender trailing the cutter by taking a path *underneath* the screen, specifically between the screener and the basket. The objective is to concede any potential perimeter jump shot while maintaining a position that denies direct access to the paint and forces the cutter towards help defense or a contested two-point attempt. Executing 'Go Under' demands precise timing and body positioning. As the screen is initiated, the defender anticipates the cutter's path and dips their shoulder, slipping tightly past the screener's hip closest to the baseline or low-post area. This keeps the defender connected to the cutter's back hip, preventing separation. The goal is to 'shrink the floor,' making it difficult for the cutter to drive or make a clean pass into the lane, effectively funneling them away from high-percentage scoring areas. This strategy is a testament to effective defensive scouting, as its viability hinges entirely on the offensive player's inability or reluctance to shoot from the perimeter. This coverage is a crucial component of a team's defensive scheme, particularly against teams that utilize screening actions to create driving lanes for less proficient shooters. It directly contrasts with 'Go Over' (where the defender fights over the top of the screen to contest a shot) or 'Switch' (where defenders exchange assignments). By understanding the offensive player's skillset, a defense can strategically invite a low-percentage shot while safeguarding the interior, thus dictating the offense's tempo and shot selection. It’s a calculated risk, trading potential perimeter space for guaranteed paint protection, underscoring the importance of defensive principles like 'protect the rim at all costs.'
