I would take Strome as a reclamation project, but I wouldn't give up anything major for him. Especially since he is effectively a rental like Bennett... He is not worth that 3.6 mill QO. In fact, I would probably look at him more as a UFA TBH.
But I will play along, and include De Haan in there too since we are apparently looking at him (even though I don't think he is any kind of real upgrade).

C/LW Dylan Strome (50% retained) - 1.5 mill
LD/RD Calvin De Haan (50% retained) - 2.275 mill

LW Nick Ritchie - 2.5 mill
LD/RD Travis Dermott - 1.5 mill
C Semyon Der-Arguchintsev
2nd round pick 2022 (TOR)
Personally, I easily turn that down from the Leafs' perspective, but I probably would say 'no' if I was offered less from Chicago's perspective.
