Its so coaches dont have out players to intentionally waive a face off in order to get their linemates a little extra rest after a bad icing or something. Theyll get a warning but not thrown out of the face off and if they do it again a penalty. it's kind of a cheesy tactic to begin with tbh im glad they're addressing it. I don't knowif they do it on american broadcasts but they always point it out on CBC. Ice the puck send in Bickell to intentionally get kicked out then Toews takes the face off getting all 5 dudes on the ice a little more rest.
