You're correct, that was the thought before. It may still be but just reading body language on the ice he and the Bo (the two rumoured "sides") seem to be cool. It feels like Miller is just that kind of personality, rather than him being an actual problem in the room.
But again, it could be Miller all along. We just don't know. I wish the front office would take some initiative and deal with it already, though.
It feels like there's been "rift" talk about the Canucks locker room off and on going all the way back to when the Sedins were still here in their finals years. It's been pinned on all sorts of different guys over the years, with all manner of different imagined "battle lines" drawn speculatively by the fans. Young guys vs Old. Bo vs Pettersson. Miller vs Bo. Everyone vs Virtanen. Upset over Tanev and Markstrom not being re-signed. Sutter vs Pettersson and Hughes. Gaudette vs his Wife's face. Hamonic vs the Vaccine. Garland has a toxic attitude. Edler vs Coach Green. Juolevi's laziness drawing everyone's ire. Beagle and Eriksson freeloading. Gudbranson and the cool kids was in there somewhere. Ughhhh...i'm probably missing a dozen more speculative conflicts and rifts.
Alleged culprits come and go, the perceived rifts shift constantly in the minds of fans and media, and we never really get any concrete evidence of exactly what's going on. Nor does management ever seem to do anything that "resolves" the apparently perpetual conflict amongst the team in fan's eyes.
But yeah...we really just don't have a clue. It's not even clear that their
are these perceived deep divisions among the team. The one constant through all these years and different players and alleged "rifts" though, has been a team that from the outside at least...certainly seems very emotionally "volatile". Prone to some kind of weird bipolar sort of motivation and quality of play. That leads fans and media to continue fanning the flames of speculation about what's really going on. But it's also entirely possible that it's all just fabricated melodrama.
