Who said 'this is a football'?

Legendary football coach Vince Lombardi.

When the Green Bay Packers football team hired Vince Lombardi as its new coach, he was intrigued with the challenge of turning the franchise around. He began leading practices, inspiring, training and motivating. But at one point in a practice, he just got so frustrated with what was going on with the players that he blew the whistle.

"Everybody stop and gather around," he said. Then he knelt down, picked up the pigskin, and said, "Let's start at the beginning. This is a football. These are the yard markers. I'm the coach. You are the players."

He went on, in the most elementary of ways, to explain the basics of football.
