Top center for past Bergeron era

You call that a premium?

Yes. Or at the very least I've hard time thinking what should I add there to still keep it realistic if we consider what we've heard from journalists and what they expected to be Sabres' ask. Consensus ask I've seen is two established NHL players, preferably under 25 year olds, two prospects and a pick - package total value around 4 firsts.

I could replace Frederic with Studnicka as BUF would probably require a solid C prospect too, but that's about it.

Bruins have the worst prospect pool in the league. Sabres want an all prospect return. So they are obviously not going to get Eichel.

Most likely. They're just a team with a need for future 1C as their core is aging.

They can try in 5 years when he’s a free agent.
