Can you explain why a preseason tournament counts? The whole point of preseason is to try formations, player positions, etc. before the games that matter start. It does not make sense to have a preseason tournament count, when a non-tournament preseason game does not count.
This is true of all HS sports - preseason tournaments count on records. Might have to do with paying officials and charging admission. I don't think officials get paid for scrimmages or teams charge for scrimmages, but they do at tourneys. Not sure of the 'rule' per se, but know that preseason counts on records.
Sometimes it's a bit unfair to smaller schools based on their records and missing players from basketball, wrestling, cheerleading, etc. However, it is not where you start, but where you finish that ultimately counts!
