 You could walk one player on at any time, but if you were going to make a substitution, you could only make one per quarter. So what the coaches ended up doing, of course, was taking the entire team out with about two minutes to go in each quarter and resting those players. And we did, in fact, have to play both ways, including special teams, kickoffs, punts, all that. And it was a very unfortunate time for most of the kids that had been recruited who hadn't played both ways in high school.
