To use a real life example of where game management, or a lack of it, caused a huge problem, I observed on a 5 to 4 promotion where the referee had done as well as he could do in a game that was almost a cricket score. Well into time added on, 8 minutes from memory, one of the winning team attackers bizarrely decided to shield the ball in the corner. I was stood with one of the assistants, an ex EFL referee, and we were both saying "find a foul" as we could see the threat unfurling on the far touchline. He didn't, a defender got fed up and went right through the attacker, and all hell broke loose. It was all so preventable, for starters it was a cup game so why he felt the need to add the time on when no one wanted it was beyond me. They also lost the player that made the challenge, and arguably one that committed VC after. They also lost a chunk of their own time as it ended up as a county appeal hearing, in the days before they were online.
