If they think Nisky is on decline AND Jensen can play with Orlov and tougher matchups they can dump Nisky as a part of mid term plan of winning another cup.
Say "Ovi and Backy are old lets setup them with better chance of winning in 3-4 years down the road".
In this scenario its hard to see Niskanen as key player even with low salary.
On the other hand, trading him now possibly lands a good prospect who can have impact even beyond 8-19 career (doubtful, but the chance for one player should be there).
The risk is only worse results next year, i would say. Not significant at all. Not the biggest factor too. Can still make a trade at deadline and bring another jensen-type.
