Just before reaching arbitration the Golden Knights and William Karlsson reached an agreement.
Since the contract is a one year deal, Karlsson and the Golden Knights can not sign a new long term extension until after January 1, 2019.

When the contract expires, Karlsson will remain an RFA with arbitration rights.
The Golden Knights held the cards in terms of how long the deal would be. Arbitration can only award a player a 1 or 2 yr deal. Since Karlsson filed for arb, the team gets to pick the length. VGK likely chose 1 year to keep him an RFA. 2 would have made him a UFA at contract end.

William had a great year for us and we are excited to now have him under contract for next season. -George McPhee
I’m happy to have my deal and we don’t have to speculate other things. I want to prove that I can do it more than just once. Hopefully I play good and can look at a longer deal in the future. -William Karlsson

Great job explaining the difficult.

Wow – I think this is almost a perfect compromise all around. Karlsson gets a big raise as a reward and a chance to show last season is no fluke. Vegas keeps another year of RFA/Arbitration Rights with Wild Bill.
If Wild Bill can come close to replicating last year’s success GMGM will feel much better about giving a hefty long term deal and giving him money for a top center. If he regresses (and he probably will) then they can settle on a decent long term contract that makes sense for both parties.
And if it does end up that this was a one year fluke never to be seen again, then we can go from there.
But if I would prognosticate I expect with his speed and two-end abilities he will have a good if not great season, and will probably end up in the long term $7mil range.
