That 6-quarter rule is going to be an administrative nightmare for somebody. Does one play in a quarter constitute playing in that quarter? Who's going to keep track of how many plays and in which quarters a kid played? I can't wait until the end of the year when some team comes forward claiming a kid played in more than 6 quarters in a week and that this should result in a forfeit for the kid's team, which then results in a loss for that team, which then changes the Category a team is in, which then affects another teams Power Ranking Average, which then determines who makes the playoffs (or, if the new rules are in place, affects a team's RPI, which then determines who gets into the playoffs and/or who gets to host and who has to travel).
I can see it now. "Uh, Mr. HUDL, there's a process server at the door with a subpoena who needs digital copies of all your varsity and JV game film on Random High School to determine if Johnny Jones played in more than 6 quarters in any week this past season."
Administrative nightmares aside, what's a reasonable recovery period? In most counties, don't they play JV games on Thursdays and Varsity games on Fridays? Playing in two games on back-to-back nights is going to be hard on kids. Yeah, I understand that kids who play 4 quarters of a JV game one night aren't likely to get much playing time the next night in the varsity game. And kids who are expected to play 4 quarters of a varsity game probably won't be asked to play much in the JV game the night before. But, still... coaches looking to gain an edge or win a game have been known to do things that aren't necessarily in every kids' best interests.
By the way, how are OT's handled? Are they considered an extra quarter?
