He's my favorite player, and one of the few reasons the Sharks are tolerable to watch, but the org would be wise to let him go. I also think they need to look at moving Meier. If you move those two before next year, you're probably looking at a bottom 5 pick in a really good draft.
On the other hand, you need some quality vets in the roster to bring guys along. Hertl is the perfect guy to insulate someone like Eklund. I'm not sure that Eklund-Couture-Dahlen, Balcers-UFA?-Labanc is going to result in anything other than getting shelled. Of Equal importance there is no size, and none coming. Need to prevent Eklund from getting bullied. Not that Meier (or especially Hertl) are tough, but their size would help insulate the small prospects.
The Sharks seem to think the fans won't tolerate a rebuild/tank, but it's happening anyway. May as well embrace it, and look to shorten it. A lot has actually gone okay this year. No one projected Meier as an elite winger, Karlsson (when healthy) back to #1 D level, Reimer ended up a legit starter, decent pick ups that were low cost in Barbanov, Dahlen, Balcers, and Bonino, Ferraro improved, and Middleton ended up being surprisingly solid.
More importantly, I can't see things possibly going 'more' right next year particularly with 42% of the cap (EK, Burns, Vlasic, Couture) likely to get progressively worse.
Even with Hertl, Barbanov, and Meier returning, I think the Sharks are likely bottom 5-7 next year.
One other thing, I expect is feeling down because he knows it's time to move on.
Blow it up.
