#1 isn't happening because of the reported animosity v. Melnyk.
#2 is possible, but...remember all the character Murray and Dorion have been adding to the team? Remember the character and leadership this team is vaunted to have, from Boro to Stone to Phaneuf (when he was here) to Smith and so on? So with aaaaaaallllllllllll this character, not one of these dudes could step in, mediate, settle things down right? But they didn't.
It's not about someone being poison in the room. It's about the team being shit, with contracts given to marginal players and extensions that are given to players for loyalty reason rather than productivity reasons. That's it.
Clean up the front office, clean the locker room of barnacles like Borowiecki, Smith, Ceci, Ryan and go from there.
But to do that takes money and will. And this team lacks both, and has for quite some time.
