Interesting responses. Like most of you I feel it is too soon to extend a contract.
However, let's assume the trajectory continues at or near the current pace.
I would consider offering Gagner a contract that would be value, only if it does not included a no movement or no trade clause.
I would think of a Gagner signing as a protection piece for the Las Vegas expansion draft. By exposing Gagner at a reasonable number, Las Vegas would get a good player that helps them get to the salary cap floor, and could provide scoring and leadership.
This would effectively shield one other player that Columbus would otherwise lose. As it stands right now, I think the most likely player to come off the CBJ roster to Las Vegas would be Matt Calvert or William Karlsson.
If Gagner does not get selected at the expansion draft, he could be used as an asset at the entry draft to acquire a better prospect or draft position.
I think signing Gagner could strategically strengthen Jarmo's hand for all the opportunities beginning at the trade deadline this year. Gagner's play has certainly brought more value than $600k annually.
