Financially ... there is something I didn't consider that actually would work. I think it'd be fairly attractive to a team like Arizona or Buffalo that needs to get to the cap floor. Those teams love higher cap hits with lower actual money. There would have to be a 3rd team and possibly a 2nd trade unless San Jose was willing to take Faksa.
Faksa would have to go to SJ or a different team in a separate trade. A 3rd team would have to be involved with SJ and Burns so that 50% is ultimately retained. SJ can retain some or the 3rd team could just fully retain 50%.
Let's say a floor team retained 50%. They'd be getting a fairly significant benefit of a $4 million cap hit and only owe Burns $1.5 million. For the next 2 years, they'd have a $4 million cap hit while only paying him $2.5 million. They're not going to do it for free though.
I honestly think the only way this would work is if SJ takes Faksa as the return for Burns with minimal or no other assets, and then Dallas and/or SJ have to pony up assets to the third team.
Honestly, two 37-year-old defenders would be insane, and Nill wouldn't go over $4 million for Suter. I can't see him having $10 to $12 million tied up in two 37-year-old defenders. Hell, I can't see nearly $8 million honestly, but I think Burns at $4 is the only way it would work.
It's possible, but Friedman is right, it would take some gymnastics and pretty much the TB/McDonagh situation where SJ is giving the defender away.
