I feel your pain. My son is an eigth grader who has been playing since he was four. He plays for his middle school, plays traveling AAU ball and now is working out with the high school players to get ready for his freshman seaon next year. I tried to play him one on one a couple of weeks ago and he absoloutely ran me ragged. It was a joke and beleive me my wife was laughing so hard she was crying watching us play. Sad part is, I used to be a decent athlete and my 13-year-old was crushing me. Took about a week for the soreness to go away, still trying to recover socially and mentally!
