Football seems like a pretty simple game of feet and inches, but Jason Garrett wants to make sure that his players understand the mathematical side of things on the gridiron.

Running forward six yards is not the same thing as running six yards on an angle, of course.

Check out the video below to hear why Garrett says his players should understand one of the basic elements of geometry.
