A great definition of a "coach" from Jim Tressel:"My job as a coach is to do more than just teach the Xs and Os of the gridiron. I recently heard someone explain how the word coach came to be applied to an athletic context. The etymology of the word, at least in part, comes from the old stagecoaches that were used to transport mail, valuables, and people before the advent of motorized transportation. Whether a coach was drawn by a horse or a steam locomotive, it carried or conveyed something or someone from one place to another. If you put yourself into a coach, you knew you would end up at your desired destination. "
