I imagine the thing(s) holding up the EK trade are Grier absolutely refusing to budge on salary retained--I don't think he's really asking for a colossal haul *unless* he's forced to retain a huge chunk of salary, then he'll ask for that kind's ransom, imo--and the fact that the Pens need to find a landing place for Petry because it makes no sense to keep him as a bottom pairing blueliner, and his salary is going to go a long way toward off-setting what EK's final cap hit is going to be after the number SJ is going to be comfortable with retaining; which I imagine will probably be like $8.5-9 million.
I think Dubas has tabled his offer, Grier is trying to hold fast when it comes to a number he won't exceed retention-wise, as well as waiting to see if Carolina will up their offer to be competitive, or beat, what Pittsburgh has offered.
If I had to guess, I think it'll either be EK going to Pittsburgh once Grier relents, knowing he can't really get any more suitors due to EK's NTC and he doesn't want to risk cratering EK's value with a potentially bad season or injury. The other conclusion is, I think, Grier just holding on to EK and rolling the dice that he'll find more options as time goes on, and hoping EK doesn't get hurt or have a massive drop off in play/production.
It's annoying. I wish it'd just get done with one way or another; Grier trading him here, or the Pens breaking off talks and looking to make changes elsewhere. But I'm just a dumb fan who doesn't know what the f*** is going on.
