Good grief the officiating sucks enough with 2 refs does anyone really think it will somehow miraculously improve with 3???? Get real. There aren't enough competent refs to make the 2 ref system work as it is, going to a 3 ref system will just make it worse. Think of how expansion waters down the quality of players in the NHL, the same thing will happen if another ref is added to the mix.
And while I'm ranting about the officiating- if I was on the NHL committee for officiating I would introduce a rule that if the ref closest to the play does not call a penalty then the ref farthest away
cannot call it. It drives me crazy (not that I have far to go) when a ref right on top of the action lets a penalty go but the guy 25 feet away raises his arm.
