Probably was referring to Jarmo's management and coaching personnel moreso than the players. They cleaned house so obviously the owner felt the same way as Laine.
Just based on play I would guess guys like Provorov only care about the NHL pay and don't put any effort into improving or winning. Just based on the fact that he only shows up to his potential in contract years.
Could also be calling out the coaching and management for dicking around all the young guys who were hungry to win and play in the NHL in favour of scrubs.
Could also be calling out the fact that the GM didn't add much to improve the roster when they had a decent mix of youth and vets.
Either way Columbus dumped a bunch of guys in the off-season/after firing Jarmo. Boqvist, Bemstrom, Bean, Roslovic, Texier, Gaunce, etc. Guys given big minutes and some of whom aren't even in the NHL this year.
It is, however, unlikely he was calling out Werenski who has been one of the lone bright spots in Columbus for years.
