I was not at the game, but I was told he was at the scoreboard side of the fence watching the games and actually called a coach out by name and said something to the effect of "that's not working, try something else." He went back to the school after the games and went over everything he saw that wasn't done correctly. As part of that conversation, "a lotta mommas were upset." haha
He didn't do it in a mean or disciplinary way. More like, this is what you did wrong, I'm going to show you what I expect.
The middle school, JV and varsity all practice together for the warmups and fundamental aspects of practice. Obviously, they break up into their respective groups for everything else. If you look at this clip, you'll see the little kids on the far end. The ones in white helmets were the little league kids(7th grade) brought up to the middle school team after the little league season completed.
