The football referee has only one job. To keep the peace. It's a Hobbesian reflection of football's British roots. Good referees only call the fouls that matter and the great referees make fewer fouls matter because that's what the fans deserve.
Imagine if Howard Webb had sent off Nigel de Jong in the 28th minute of the 2010 World Cup Final. Although he's on record as saying it was clearly a red card offense, he didn't see it that way in the moment and a world of fans were treated to a memorable match versus an hour and a half of Spanish tic-a-tok-a against ten players.
