I doubt you will get any Tennessee teams to attend, this is our Mandatory dead period from June 26 - July 9. According to TSSAA, Dead Period: No coaching, observing, or contact between coach and players in sport involved. There is no practice, no open facilities, and no weight training/conditioning.
If a team from TN does attend, they will have to do so without any of their high school staff.
Back it up a week and I'm sure you'll find plenty of TN teams.
