College boy Jason Garrett wants his team to spend some time in training camp brushing up on the Pythagorean theorem. His explanation is remarkably logical!

"It's an important thing to understand...If youâ€™re running straight from the line of scrimmage, six yards deep, thatâ€™s a certain depth. It takes you a certain amount of time, but if youâ€™re doing it from 10 yards inside and running to that same six yards, thatâ€™s the hypotenuse of that right triangle. Itâ€™s longer. So they have to understand that it takes longer to do that. Thatâ€™s an important thing. Quarterbacks need to understand that, too. If youâ€™re running this route from here to get to that spot, itâ€™s going to be a little longer, you might need to be a little fuller in your drop...We talked about Pythagoras. It's been going for the last few days.â€ť

An NFL playbook is already among the hardest things in the world to memorize. By the time Garrett gets to non-Euclidean geometry, they'll have forgotten what a post route is.
