Well I definitely understand the hesitation. Dahlin will probably be around 10M. Does EP deserve that? Certainly. But that number comes from a skewed narrative that he just wants to get paid and the original story was that he just wants to win. Maybe he's happy with 8M on a good team because there's not a whole lot of 10M space good teams.
Let's say it's an Eichel like return. 1st, 2nd, good roster player and A (not A+) prospect. Maybe they do cave on Savoie or Benson, JJP and some picks. That's far from gutting the farm. You have Kulich, Rosen, remaining of Savoie/Benson not yet in the NHL as well as Quinn, Greenway Mitts, VO, possibly Krebs already in your middle 6. And those are just a few that could step in as early as this season with several other guys a year or two away. You can even toss in a Kisakov or Nadeau type and it still wouldn't hurt.
Does it hurt Cozens to be the "3rd line C?" Nah. We've hashed it out on our boards. 2nd, 3rd and 4th lines had near identical TOI and very close to 1st line. There just isn't much of a difference.
I don't know how seriously Adams would make a bid and I've stated that he probably won't move prospects until he has to move them but maybe he's just waiting for the right trade. That's 3 excellent young centers to go with our talented young D core with still lots more ELCs waiting to make the team.
