When you talk about in-season coaching changes in the NHL, you don't often think of guys like Joel Quenneville.
And by that, we mean you don't often think of three-time Stanley Cup champions with almost two decades worth of playoff seasons losing their jobs during the season.
And yet that's exactly what happened to Quenneville this week. The Chicago Blackhawks sought a scapegoat after a 3-6-1 stretch that dropped them near the bottom of the Central Division, and they determined Quenneville fit the bill. So not only do we have a major -- and unusually prominent -- coaching shakeup of the 2018-19 NHL season, but we have plenty of reason to shake up this week's edition of NHL power rankings.
