“A college? football coach had a dream of coaching an NFL team. I remember a smartass player always causing trouble, in a meeting with the players the coach was visibility upset and said something like, ok, we will start at the beginning and held up a football and said, This is a football, A player asked the coach to go slower, After a moment of silence and terrified looks on the players faces, the coach busted out laughing, In the end he was offered a NFL coaching position but turned it down for the love of his team.”
