Ah yes, the Rick Nash trade-tree that built the Rangers literally forever.

Rick Nash, Steve Delisle, and a third-round pick were traded to the Rangers for Tim Erixson, Brandon Dubinsky, Artem Anisimov and a first-round pick (Kerby Rychel).

Nash was traded to the Bruins for Ryan Spooner (quickly flipped for Ryan Strome), Matt Beleskey (nothing), Ryan Lindgren (a total beast currently Adam Fox's partner) a first-round pick and a seventh-round pick.
The 7th rounder became Riley Hughes (although they received a 2019 7th rounder, they traded it for a 2018 7th rounder and took Hughes).
The first-rounder was part of a trade-up to take K'Andre Miller.

The third-rounder the Rangers got from Columbus? They used it to take Pavel Buchnevich. A player I wish was still on Broadway. But instead he was traded to St. Louis for Sammy Blais and a second-rounder (Elias Salomonsson, but the pick itself was part of a trade for Andrew Copp at the 2022 deadline). Blais was moved for Vladimir Tarasenko and Niko Mikkola at the 2023 deadline.

I'm really sorry I can't go through the Blue Jacket side, basically, Dubinsky played his career as a Jacket, Erikson was traded for Jeremy Morin who with Anisimov and others were traded for a package including Brandon Saad who headlined the Jackets' rental of Artemi Panarin (who signed in New York).
