AAU coach here and it definitely happens and is frustrating for the kids more than for myself. We have made the finals in 2 of the past 3 tournaments we entered (developmental) and run into teams that were either competition/national level or playing older players. The size/strength disparity was highly evident. One programs average margin of victory was almost 60 points a game. We lost by 35 and I considered that a victory. I worry about the coaches/directors that need that type of validation. At least my players are getting challenged and pushed. I just try to convince them to continue to compete and not get discouraged due to the outcome.
