The members of the team had rolled out the resilite mats in the back gym. The air was barely heated, so they had been hard to the touch as the boys rolled them in three straight sheets. The kinetic energy of a pair of teenage boys transferred to the friction of the shoes applied a sheering force that would separate untaped mats. That was acceptable during a normal practice, when the mats would be shared by a half dozen pairs at once. During a real match they would be taped together, to prevent them from separating during the bouts. The tape was an expense that the cash strapped athletic department wouldn’t waste on a practice. But there was no risk of separation during the opening half of this practice. The mats were rimmed with spectators, the members of the team focused on the two participants in the center. During a normal practice, the mats might be rolled out with either side up. The lesser used side had five circles, laid out like the dots on a die showing 5.
