Then, the value of a yard can be inferred from field goal kicking probability, for instance, 15 years might be worth a point if it drops from 0.75 to 0.42, as we move from a 45-yard attempt to a 60-yard shot.

We shall find that the second number exceeds the first by as much as a factor of two. Players and, by implication coaching staff, are putting far too high a value on possession relative to yards

The calculus for the 11-yard gain reads, which is still way too high a value (in yards) to put on possession. However, more detailed variations on this calculation are presented in Cotton (2021),

Conversely, defensive players need not suffer one extra concussion to bring about an abrupt deceleration of the ball carrier. Let them get the 10 yards, or 11 if necessary. And the implication extends beyond individual player decisions. Offensive and defensive teams should design plays to make the and yard gains more likely, and the middle ground less so.
