A post-match analysis tool using basin-hopping global optimization to find individually adjusted defender positions (within a 5m constraint) that minimize spatial xT. Identifies specific repositioning recommendations for each defender to neutralize threats that were exploited. Key finding: mathematically optimal positions sometimes contradict conventional coaching (e.g., leaving a marked player to protect central space).
For each frame where the team conceded a high-TAx situation: fix attacker positions, allow each defender to move within a 5m radius, optimize positions to minimize spatial xT. The output is a counterfactual "if defender X had been 3m to the left, spatial xT would have dropped by 15%."
A position optimizer minimizing spatial xT sometimes recommends leaving a marked player to protect central space. The math says the space is more valuable than the man.
