Losing him for nothing does not help us. Ask Isles fans if they enjoyed watching Tavares walk out the door and receiving nothing in return. My first choice is to re-sign Karlsson, but it’s up to him. If he doesn’t want to re-sign then it’s a no brainer for me. You have to move him. You might get an underwhelming return, but that’s still better than nothing.
Tavares was never on the market so Isles fans can still delude themselves into thinking they could have gotten a great deal for him, and perhaps they could. Who knows?
On the other hand, Karlsson has been on the market for 6 months and from the rumour mill we have a pretty decent idea of what his value is right now. It's not good. Vegas won't entertain adding Cody Glass, Dallas won't include Heiskanen and Tampa won't include Sergachev. We can't get a building block piece for someone who is arguably a top-5 player in the league.
It would be a disaster to trade Karlsson and get something like Julius Honka, Jason Dickinson and some draft picks back. Same applies for Cal Foote and Taylor Raddysh, although Tampa's prospects are quite a bit better in this case.
So I say shut down trade discussions immediately unless one of the interested clubs wants to come back with an offer that includes one of their top prospects/young players. In the meantime, try to figure out a way to keep the guy in the fold. If the deadline rolls around and the team is a trainwreck I guess you can reconsider some of these junk offers at that time.
No need to tank our season before it even begins by making a bad trade under the guise of 'eliminating a distraction'.
