He hears it, the other players hear it. If they don’t know what they did wrong, ask the team.

I ALWAYS started off by saying “I’m not picking on XYZ, because all of you do it, but what could you have done better” or “what was the better option?”

I also tried to cut the word “good” from my vocabulary. It’s easier than it sounds. I hate the idea word good. Kids can’t learn if you say “good” after a drill. That’s a personal preference that you didn’t ask for, but oh well.
