From xG to Pitch Control Surfaces
While Expected Goals (xG) measures the probability of a shot resulting in a goal, modern tactical departments focus on Expected Threat (xT)—a metric quantifying how moving the ball from one zone of the pitch to another increases overall scoring likelihood over the next five phases.
High-resolution optical tracking feeds running at 50 frames per second calculate each player's acceleration vector and kinetic cone, generating dynamic "pitch control maps" that reveal whether an opponent is truly covering a passing lane or merely occupying visual space.
