Oh the carnage!
Last season saw exactly zero NHL coaches fired in season. In a league where chaos is the norm as far as head coaches go and there are usually at least two to three coaching changes during the season regardless, I remember seeing Kevin Weekes commenting on the NHL network that perhaps GM's have finally developed patience with their coaches and are going to allow coaches a longer leash to get their message across.
Nope. 2017-18 was just a blip.
