IMO the long term scenario the Rangers should be hoping for, within reason, is this:
Panarin - ___________ - Kakko
Chytil - Andersson - Kravtsov
Barron - Howden - Lemiuex
With a 4th line being replenished by ELCs and cheap free agents, maybe veterans like Fast. Kreider, Buch, and maybe even Zibanejad traded to put the team in position for long term #1 center or #1 defenseman assets.
I'd be hoping to get into range for a guy like Byfield in this very draft, and possibly using the above referenced assets (Kreider, Buch, our own first, a future first) to do so.
