How many games are you allowed to schedule? 18 plus two tournaments? If you make championship game of the Viking Cup (5 games) and play in the Fort Mill Invitational (4 games), that's 27 games. Make it to the state championship (5 games) and that's 32 games. I'm not even counting the three scrimmages.
So, from February 23 - May 11, a team would play 32 games in 78 days. That's fairly demanding, no wonder we see ACL's snapping.
