29-14-4 compared to 10-21-4 that is the record for the Arizona Coyotes last season when they scored first vs when they gave up the first goal. Those are two very different records. The Coyotes only scored 62 goals in the first period last season, the lowest out of all 3 periods, but that does not mean they can not change for this season.
It is all about starting off strong. That is all you need to do in the NHL, and the Arizona Coyotes need to try to do that more. Through the first 4 games of the season this year the Coyotes only scored first once.
