A picture's worth a thousand words,so here's a few pictures and not too much waffle.
I've looked at every individual passing attempt by every quarterback in the playoffs since 2006 and I've noted both the distance traveled by the ball through the air and if the pass was completed or not. I've then produced a regression equation for air yards thrown and completion rate and plotted this curve for every post season quarterback. Below is a plot for five of the most prominent passers over the period. To illustrate how to use the graph when passing to targets five yards behind the line of scrimmage, Brady, Manning(P), Roethlisberger and Rodgers are all completing at around 85%, while Rivers is down around 70%.
