Visualization of \( \tau _{\text{df}} \) at a certain time as a contour plot over a range of 2Â s. Players in offense (i.e., ball possession team) and defense teams are depicted using blue leftward and red rightward triangles, respectively. In this situation, the player on the right side near the halfway line has the ball and is trying to pass it to the other side.
