Aside from Jonathan Toews, Patrick Kane and Seth Jones, who all have "No-movement Clauses," the team is open to listening to trade requests on any other player on their roster. Kane and Toews are also entering the final year of their $!0.5 million dollar contracts, so with the right fit, those two could be rental options at the Trade Deadline next season (barring a miraculous season from the Blackhawks).
That means Chicago's top-scorer, Alex DeBrincat is on the market; he collected 41 goals and 37 assists last season and will be on his final year of a $6.4 million contract, in which he will be an RFA after it expires.
Other notables include Kirby Dach, Dylan Strome, Dominik Kubalik (who are all RFAs currently) and Jake McCabe, who has three years remaining on a $4 million contract.
