Buffalo declines IMO

Not to mention that RNH declines as well...why would he sign an extension in Buffalo (Unless it was MASSIVE), when he's going to be a UFA in a couple of months?

If the Columbus trade is done before expansion the jackets instantly reject. There’s no reason for them to make that trade before expansion.

Sabres would decline for sure. So many teams could easily outbid this.

It helps expansion problems for both EDM & CBJ. Columbus gonna have to protect one or Korp or Elvis, ones gonna be exposed. As for EDM, Caleb Jones is a likely candidate for SEA to select. So edmonton gets value out of Jones, CBJ gets value out of one of their goalies before letting one get exposed

Sabres could do better

It doesn’t help Columbus at all. Elvis is exempt.

Y'know, there's this very helpful thing on this site, under "Interactive", called the Seattle Expansion Draft Simulator. If you go to it, you can see which players are potentially exposed and which are exempt. It's quite handy.
