Probably drop the cost slightly. Go full traditional court for the Senior division. Try to market the basketball program to more age groups from 15 to 17.
Would try to use two venues, so the games weren't so early in morning, and not too late in the afternoon.
Go to all the middle schools and freshman high school basketball programs. Talk to the coaches. Ask them to hand out pamphlets to the i9 sports basketball programs to the kids that didn't make the team. Encourage them to come and work on their skills year round.
Communication has been outstanding given all the weather issues. I like how the account has the schedule ready and can be easily shared with others. I also like how snacks are organized through the account portal as well.
