We'll disagree on this. I don't care if the person was a player or not, they need to understand how to manage a game from a referee's perspective. Almost anyone can learn the laws of the game and be able to apply them in a black and white manner...but we all know the game is not static nor black or white EVER. You need people who have a passion for the game and who want to make sure it's conducted in a fair and safe manner.B) I couldn't disagree more about this. We need more players as referees.
And I will say, my son calls games in a different manner than I do. Of course he played, fairly high level and HS from the age of 6 on. He does call games from a player's perspective. He and I disagreed on the controversial Arsenal RC a few weeks back where the Arsenal player caught a player on his ankle with the studs. He said it lacked the force necessary to be considered SFP. I understood the referee's perspective in real time and couldn't see anything on replay that VAR could deem a clear and obvious error.
What I will agree with you on is there are people who referee for the paycheck and you can tell. They don't need to be out there.
