Eichel had a Hart-worthy season last year, that was both with an awful coach and the dumpster fire that is called Buffalo.
His % share of the point total of the team was sky high, much higher than Matthews, and closer to McDavid.
If Eichel plays with a healthy neck for Buffalo next season, and Reinhart + a good goaltender + a good coach are a part of this team, then they are in playoff contention.
Yes, let them sulk.
However, I'm not sure if Adams/Pegula are in the works of making a wrong decision, that is they trade Eichel for scraps.
