My idea around it was the Bruins could be fine with Zacha or DeBrusk at LW in the top 6, and they have Kane and Pastrnak in their top 6. If Kane were to waive his full NMC for Boston, then I think there would be a chance there to extend him.
I don't want the Bruins to trade Hall by any means. I included Hall because I think moving him for a similarly aged player who would have the same if not more of an impact in the playoffs would also free up cap space to activate Forbort to be cap compliant, and the Bruins wouldn't have to sacrifice the future (picks and prospects) to do so.
Again, I do think the Blackhawks could probably fetch a better return for Kane.
Kane is 3 years older. Hall is a bird in had on a Cap Friendly deal.
Hall is currently outscoring Kane 2-1.
There are other ways of freeing up cap to activate Forbort.
I wouldnt do the deal.
