Recently, we learned that Don Waddell from the Blue Jackets would like to receive an NHL-caliber player, not just a prospect, in return for Laine. He might also be willing to retain part of Laine's salary in the trade.
However, according to Eric Engels of Sportsnet, who discussed it with Tony Marinaro on the "Sick Podcast" yesterday, the Canadiens' interest in the Finnish player might not be very high.
In summary, while the Canadiens have some interest in Laine, it will depend on the asking price and the portion of the salary that the Blue Jackets are willing to cover.
