Imagine talking with your friends about who is the best professional
athlete. Now, imagine talking to them and not saying anything
about numbers or statistics. What a boring conversation that would
be! Without numbers, we could not evaluate the performances of
individuals and teams. For example, every football game is full
of numbers used to compare the players and the teams. What team
scored the most points? Who ran for the most yards? Who has the
most touchdowns? What is a player’s passing average?

As the volume of numbers used to describe sports increased, we
developed tools to measure, calculate, and store them. Stop watches
measure the speed of runners in the 40 yard dash. Cameras film
the form of a quarterback’s throw. Computers compile, calculate,
and store numbers for later evaluation.

A study of sports since the 1970s shows that every successful
move or technique is based on a law of mathematics and science.
