I said that to a ref when I was around 9. It was at a division 2 men’s game. He threatened to kick me out until all the fans around me got on his case.
He fair caught a ball at the 2. He later fumbled at the 8 (that is where the ball was placed)
The player didn’t listen to the coach. It’s that simple. You can tell a player anything. Them executing is not a guarantee
