ESPN has a nice article up on Peter Walton, the new "North American Refereeing Czar" as they call him. There are some interesting quotes, but he really focuses on the feel of the game and tweaking small things referees are doing to try to improve their performances. One quote that jumped out at me was: "When a player makes a challenge that endangers an opponent's safety and everyone in stadium just goes "Ouch!" the law dictates "Red Card." But if the player already has a caution and the challenge is merely worthy of a second yellow, I would prefer to see a referee employ a management technique: talk to the player, calm him down and let everyone know that the he will get another card if the offense is repeated." For Walton, a referee's prime value is to "give the game every opportunity to take place on the field." I think this shows a lot about his philosophy and what we may be seeing as the new expectations.
