Max Bultman of the Athletic answers some fan mail,
For Eichel, one of the league’s top scorers under contract for five more years, the cost would be immense. It could mean a deal headlined by Lucas Raymond or Filip Zadina, the No. 6 pick this year, plus either another current top-six NHL forward or another high draft pick or top prospect.
It’s possible Eichel’s neck injury changes that price a bit, but the safe assumption is that Buffalo will be able to command a mint for a 24-year-old right-shot center who has been near or above a point per game for five seasons.
