How? Its simple. There isn't going to be a 1C moved this off season, very likely, and that would be because one isn't available. without an incoming 1c they have Kuzy and Backstrom. If Kuzy is traded, Backstrom's hip has been fixed. If its still a problem, ask Lavy who he wants to create offense and run his pp. Eller or Kuzy? He trusts Eller more defensively but not with the power play. He took him off it. Remember?
The only way they can't "roll" with Kuznetsov is if Ovechkin and the rest of the locker room want him gone. You want to blame Laviolette. The only way Kuzy is gone at this point is if the players want him gone. IMO.
After watching Ov snap at Samsonov in full view of the cameras and knowing that Backstrom and Oshie were playing in real pain and the whole Oshie dealing with COVID rules in order to play, I can imagine that the locker room feels like the trust has been broken.
