How many teams have the cap and the players wed want in exchange for ROR and would trade for him.
That's the problem now IMO.
Most teams are starting to solidify their rosters (remnant UFAs like Stepniak signing, RFAs starting to sign, etc).
I think NYR and Pitt are the best trading partners based on need and return since the Avs could take a bit more salary than they sent but that is if the Staal/Martin/Maata availability is true.
Florida made sense, but I don't by that Kulikov is still immediately available now that he is signed. Maybe later in the season if it starts poorly, but I doubt it is likely to happen before the season starts.
Then the young teams that could use another core piece, especially a captain/future captain candidate like Calgary or Buffalo, are not likely to have more than quality futures to send back, which does not fill the need we all are hoping to have fixed.
I think it will be a mid-season trade as well at this point
