I am curious to see what the impact will be on football. The popular term is "exposure". Travel 7 on 7 teams can go much further than full teams can, and can play out of season. The biggest impact is among smaller schools where kids are having to choose what sports to continue playing and which ones to give up. Far too often, football loses out. It is not easy to put a helmet on when it's 80 degrees or higher. The effort it takes to get better is too hard for some, so they choose another sport and skip summer workouts for football. Often times, it's the parents making that call too with the cost of travel teams being what they are.
