A lot depends on ownership imho. If the Melnyk's continue to own the team, I think Pierre will only get his one big trade financed i.e., a winger.
I'm thinking there won't be an addition to the defense as there's already 8 defenders on the squad (Chabot, Zub, Sanderson, Holden, Hamonic, Brannstrom, Zaitsev, MDZ) without even including JBD & Thomson.
I think Murray will be back for the beginning of the season.
I doubt there will be the buyouts and retaining that some are expecting. Those dead weight contracts are going to be difficult hence costly (asset wise, etc.) to move.
Pierre might want to make more moves, but I don't thinking the money will be there to pay for it. Hope I'm wrong. The wild card of course is a change in ownership (and owners with deeper pockets).
