I wouldnt trade Schneider at this point for any realistically available player, but Kakko or Chytil (id hold FC because we have literally nothing at C behind him) could be available in the right trade. I know people have an emotional connection to Kakko but if the Rangers arent bringing back Strome/Copp, and the team plans on being a Cup Contender next year (rightfully so) he's a trade chip. Lundkvist too, he will never have a spot on the right side here. Kravtsov & Othmann could also be available. Teams may also value Cuylle or Berard fairly highly based on their development.
I'm certainly not saying to trade all these guys, but they dont all have a future here, and something has to give eventually.
Cuylle, Berard, Othmann would be throw ins in a trade like this for an established PPG 1C. Apparently Vancouver turned down Chytil+Lundkvist+ a 1st at the TDL. The price hasn't gone down with so many teams focusing on JT with laser vision. Vancouver are retooling, not rebuilding, they want established players in their early 20s in return. So the price will be heavy both in talent, cap consequences and roster fallout.
Aho and PLD are UFA's in 2024... Maybe simply follow the Colorado/Tampa template & keep growing the kids until then, if things haven't worked out sign Aho as 1C, let Zib slid down to 2C and retool the roster as necessary to balance it all out between vets, the grown kids and incoming kids (Cuylle, Berard, Othmann).
Maybe, if given the chance, Chytil keeps developing playing with talent (not Gauth) on his wings next season, and solves the 2C problem internally. That's the thing with kids, they grow into better players with proper nurturing, just like JT Miller did.
