I think it is spelled A-B-C. They want more matchups for their coverage and the NHL caters to them, despite their piss poor coverage. It used to be one night one conference, next night other conference. The best way would be 2 east and two west games so that there would be double headers every night, or at least staggered start times so that non stop hockey.
That way even during intermissions there would be hockey being played.
