The earlier point about fear of making an error is interesting. There seems to be a subtle but important distinction between playing under control but all out and being afraid to play all out lest you get out of control.
I had a bad baseball coach in HS that was always criticizing everyone for anything. We had a talented team my senior year, but it was unpleasant to play baseball, which most of us had done since we were 6. He made us afraid to play because our focus was mostly on trying not to make some kind of error, so of course we made errors.
He had very complicated signs for HS, as if they would be stolen, a preindicator, the sign, and a post indicator. He would give the first two and then sort of brush at his belt for the third indicator for a steal attempt. If you stole, he'd chew you out. If you didn't steal, he'd chew you out. He got fired after that season.
I remember how glad we all were to lose our final game and be done with it. Looking back I wish I had quit the team.
