Why take on other teams bad contracts and cap mistakes as a clean slate expansion team, when you can make your own fresh new ones right from scratch???
But seriously...they went through the whole expansion draft, apparently pursuing a strategy of "cheaper is better than better". A "cap space > roster capability" sort of mentality. Which is at least easy to understand, conceptually. There's a grain of truth to that notion. But to then go ahead and just dynamite that sort of plan to smithereens with a contract for a #4/5 fringe guy like Oleksiak at nearly $5M long-term...Idgi. Very strange, the apparent lines they've drawn in where to penny pinch and save cap space...and who/what to splurge on.
In any case...Zadorov and his agent must be grinning looking at this. Certainly seems like something to give them a bit of ammunition in gunning for what prior to this, sounded like a kind of absurd "ask" for a very similar player.
