The team's quarterback was Ellwood Wilson, considered the "founder of Sewanee football."[1] He had come from Lawrenceville, New Jersey, where he played football before, to Sewanee in 1889. While introducing the sport to Sewanee, he was forced to use a piece of wood shaped like a football until he found a real one. Sewanee's first intercollegiate game was the first instance of the Sewanee–Vanderbilt rivalry and Vanderbilt's second ever game. The win over Tennessee was that program's first game.
