CBJ trade is the only one that seems like it could happen. Their rebuild could really use those pieces. But I bet their fans say no. The rest don’t happen

Explain how either of those players fit into the CBJ lineup.

Today they aren’t nhl ready. So they don’t fit in it today. But all 3 are good young potentials for a team that’s rebuilding. So, you would need to sign other players as stopgaps for 2-3 years probably.

Rangers have no need for Jarnkrok.

K, I think you're just unaware of the Jackets system heh. Niemela would come in at probably 6 on their RD depth chart behind Severson, Jiricek, Peeke, Boqvist, and Ceulemans. I suppose 5 in this deal since Peeke would be getting traded, but there's still 0 path to him getting NHL time. There's no having him swap to LD either since they've got Werenski, Mateychuk, and Svozil there as well as several more LD prospects.

Abruzzese would be somewhere around Trey Fix Wolansky on the depth chart behind Gaudreau, Laine, Jenner, Johnson, Marchenko, Sillinger, Fantilli, Brindley, Dumais, Voronkov, Chinakhov, Texier, Del Bel Belluz, Malatesta, Bemstrom, Foudy, Olivier, and maybe Whitelaw and Pinelli.

Neither of those guys would have anything resembling a path to an NHL career in Columbus.

The only appealing part is the 1st, which is probably fine if Peeke and Roslovic are deemed expendable, but I imagine trying to work them into a trade that returns a roster player now would be more interesting to Jarmo.

Oh I get that you have lots of prospects. The more “higher potential” guys you have in the minor system the odd are better they actually make it where you need them. And when you only have 1 spot and 3 guys that could fill it in a few years you have valuable assets to move for the hints like rentals. This timeline is also the same timeline I would project CBJ being contenders. I personally think they will be a wild card seed for playoffs as they are now and if they can remain healthy(health is the big thing). Next season for sure. Again, if you read my original post it doesn’t say CBJ should do it. Just that it’s the only one that would be close to possible and that depends and the GMs direction. I also noted that fans(like yourself) would say no. So I can definitely see why they would and wouldn’t do it.

the leaf system is vastly over hyped. Even with the Summer of Brad, Knies and Minten are probably the only 2 prospects that other team value. the rest of their top prospects are injured, aging, or small players who the league is trending away from. Why do you think every Leaf AGM is trying to move Robertson for an all star.
