I don't think there's really anyone out there currently. Best case scenario would Smith is super impressive and can handle playing like 20 minutes and spending a lot of time with PK. Then we could have something like
Smith-PK
Butcher-Vatanen
Greene-Severson
With PK getting a lot of time and the other 5 getting similar minutes
I won't even get into the goaltending because we've been over that and disagree
No way can Smith play those minutes. I'd doubt that Butcher/Vats could hold their own against 2nd lines. No way is Severson 3rd pairing. That (R) for rookie he is lugging around won't allow it.
At least early in the season, we'll probably see
Greene - Subban , if only because the coaching staff esteems Greene's ability as a stable defender
Mueller - Severson, if only because Butcher Severson seems scary,
Butcher - Vats
and just even minute distribution, OR, they try to shift Vats to the left side and go:
Vats - Subban
Greene - Severson
Butcher/Mueller - Carrick
I mean, in terms of complete defensemen at both ends - guys you want to play the most minutes - our D runs Subban, Severson, Vats, Butcher, Greene, (or maybe vice versa on the last two) Mueller, Carrick - so you've got to be trying to get all of your RHD the most minutes.
