Ha, yes, this seems like some serious stating of the obvious, but I think his point is more complex and kind of interesting: basically that the Sharks are playing the kind of open style of game, led by Karlsson, that can help guys put up points, which serves to raise their trade value at the deadline (whereas many bad teams, like the Sharks under Boughner, try to play lower-event hockey in order to eke out as many points as possible from tight games).
So the idea would be to keep Karlsson, since he has a hand in this, and pick up a few guys as free agents this summer--guys with good offensive potential but in need of a return to form, so ideally on a short contract--and then flip them for picks or prospects that will net us long-term value.
I'm not sure I totally buy into this, because with the right deal I think trading Karlsson would be the best move we could (realistically) make right now to bring back value, and trading him also increases the likelihood of a very high 1st rounder in 2024, but it's something to chew on.
