If he resigns wouldn't it have been done long ago? I don't see a scenario where re-signing would take this long even if there were on going negotiations on salary expecially given managements demeanor when it came to offering him a contract.
Seems to me like the Sens are just waiting for the best possible return before shipping him out
EK65 said (in response to DD comments) back in November that he expects to be paid what he's worth, either here (Ottawa) or wherever.
He now knows what DD received, and it seems he broke off negotiations with the Senators after they opened up, with a 10x8 offer.
Now I know this a bit of a stretch, but in order for him to know what other teams would be willing to offer him, perhaps he requested the rights to talk to other teams, in order to find out for himself, what they would offer him, in a pre-agreed extension, should he be traded to them.
Did he find a landing spot(s)? We don't know for sure, but the rumours of trade talks with a few teams seems to give us an indication.
Did EK65 formally request a trade, after talking to these teams? I don't know, it's been pretty quite, and there's a chance the more it lingers on, that he may have second thoughts... but I doubt that, but there's a chance.
OR, PD is playing world series hardball, and it determined to hit a home-run with this requested trade.
