That's $50K less than his qualifying offer, which Kaliyev and his agent could've just accepted. I guess that they gave up a little money to make it even easier for the Kings or another team to fit him under the cap.
His QO would have been a 2-way deal.
By fighting, they got him one-way money.
Ironically, one-way money might be what allows him to pass through waivers. So many teams have their own projects, they may not want to have to spend the opportunity cost of putting one for their own roster players on waivers but also risk paying Kaliyev one way money if he doesn't stick in the NHL.
There were rumors about Ottawa being interested, probably due to the Staios Bulldogs connection, but I don't really see how he is a fit. If JBD fails to make the Sens roster and Kaliyev fails to make the Kings, maybe a swap makes sense at that point because it's two players with similar one-way money.
