Agree re: Karlsson.
Panarin, I'm torn on: there are good arguments on both sides. 60/40, don't sign.
Trouba, I disagree. He turns 26 NEXT February, one month earlier than Skjei. There are absoclutely certain pieces that need to be off-limits in trying to acquire him, but in the right deal (e.g. Skjei + ADA for Trouba), he absolutely makes sense. It's not jumping the gun on the rebuild, it's simply reallocating the assets to be used in the rebuild.
It's all about the right deal. We cleared cap over the last couple of years, entered a rebuild, and we are going to lock ourselves into a big contract when we don't even know how competitive we will be? Now if we can shed the three "S" (Staal, Shattenkirk, and Smith) contracts, then oh yeah, go after these guys, both if possible. I just feel we are a year or two away from making a big splash in the FA market or big trade. But hey I am always optimistic so just hope for the best.
