I tell coaches in the leagues I run, if you ever pull your team off the field over a referee's call, it will be the last game you coach in any of my leagues. This should be the case with this high school football coach in Seattle, Washington. His team was losing 14-0 in the 3rd quarter when one of his players fumbled. The refs felt the other team recovered. He didn't. I suppose it was the ref's fault that his player fumbled.
Their first cop-out is always, "I'm concerned about the players' safety". Please. Did you ever notice none of these "crybaby" type coaches are ever concerned about their players' safety when their team is winning? Nothing like teaching your players the fine art of quitting.
