"Every new school that has been started since then has at least had some students that had a prior opportunity to participate in organized football. Coach Theriot did not have that luxury, in fact, to my knowledge, none of the 30 plus players had any prior 11 man football playing experience. He literally had to almost single-handedly do everything with the program.
“The parents really came through with getting us a field ready, with the stands and the lights you need for Friday nights,” Theriot was quoted. “When we got there for practice, we had to show (the players) where the line of scrimmage was and what a football looked like,” he jokingly added. “We learned a few plays and did the things we needed to do to look like a football team. And we did better than a lot of people thought we would, I think.”
