I also have a son that plays QB for a team in Utah County whom also attended both the Ute Shoot and BYU 7on7... outside of a delay in bracket seeding (maybe this is your flow issue?) at BYUs they were a wash imo. We used the hour they took to seed to grab lunch at Zupas, it was actually a good break. As far as access to coaches, we had Jack Damuni and Coach Gilford close by all day. I'm really not sure what you are talking about because they were both run well per our experience.
I guess if I'm looking for something to complain about then they definitely could have opened the restroom earlier.
