extremely doubtful. gonchar's out until basically thanksgiving (probably a bit longer), and they're going to make a deal for a guy of kaberle's stature? what are they supposed to do salary cap-wise when gonchar comes back?
letang and goligoski are still there. obviously the team will suffer in gonchar's absence, but trading for kaberle makes zero sense.
Unless he's out for the year and playoffs, the Pens really don't have enough insentive to overpay for Kaberle, which is what would end up happening. They have internal depth that should allow them to whether the storm, as long as Gonchar is healthy for the playoffs. Like others have said, this is a month or two at most so no need for Kaberle.
It was only a matter of time before these kind of threads started popping up.
If the Pens didn't trade for defensive help when Gonch and Whitney were out for a significant amount of time last year, they sure as heck aren't going to now. We'll be fine for a month or so while he heals, and if the team falls apart without him, it just makes Shero's decision on re-signing him that much easier.
