I've just been thinking all off-season and this reminds me of the Granlund situation. We loved the guy, he had 3 seasons of ~60pts as a young center that we needed. But the Wild GM wanted a different look and didn't feel he was worth his commanding contract (already signed to 5.75 AAV and was going to ask more the year after).
Straight up, we got Fiala - still on ELC, 2 seasons of 40pts.
It's an interesting idea because if we can get something similar, we bring in a talented forward but also get the extra cap space to spend on free agents. Both get better and a cheaper offensive forward. Plus Rossi is younger than Granlund at the time so we might be able to squeeze out more
But who fits that bill? Peterka doesn't really as he's already going to command a huge raise now.
