Were the "fake" injuries when Clayton was on offense or defense?
The Clayton coach was at Myers Park at one time. They played at Richmond in the playoffs and he had his defensive players faking injuries late in the fourth quarter in an effort to get the ball back. There was no rules-based recourse at that time to address it.
His methods were reported to NCHSAA, who forwarded it to the NFHS rules committee. The result was a rule change giving the offense 40 seconds on the play clock (instead of 25) for defensive injuries, as well as defensive penalties, or administrative stoppages for which the defense is responsible. As such, the offense has more time to snap the ball and can more easily milk the clock.
As a wise man once said, "You can make every rule in the world, but you can't legislate honor and principles."
