I've been wondering about why Perrault gets so limited minutes for 2 years now. My speculations have varied ranging from PoMo incompetence to an underlying back injury which makes it necessary to limit his minutes in order to keep it in check
I think it's Maurice though... he gets way too comfortable in his 'preferred' lineups and usage. When there are injuries, he has shown he can actually coach sometimes, but how rigid he is with his healthy roster is baffling. I'm not saying he should be mixing things all the time, but having some guys glued to each other seriously limits his options. Basically he has shown he can 1) swap Connor and Ehlers between 1st and 2nd line 2) move players in the 4th line in/out from pressbox. That's about it.
Also that whole bit about Laine-Scheifele-Wheeler having "bad underlying numbers" or whatever when they have played like 3 periods total together over the past season and a half is such a completely dishonest BS reason. Where's the sample size in that? Especially since 2 of those 3 periods were first game back for Scheifele after a long injury, and he sucked that game. And let's face it, Connor doesn't exactly benefit the underlying numbers of any line he's been on recently, yet he seems Maurice's no1 option for the 1st line. Granted, Ehlers is down currently, but somehow I always get the feeling for whatever reason Maurice really prefers Connor there, despite Ehlers giving better results and underlying numbers. He's the coach, he has the right to opinions and to making those decisions, but he shouldn't ever try to back them up with intellectually dishonest BS like "underlying numbers" when clearly he doesn't really care about those. There's just too many things that would be done differently if he did.
