Its an internet discussion board, lol.
If you can find a single Sens fan who expected Norris would return a long-term piece + a high draft pick, I will eat my hat. DJ (edit: Green, not DJ) and Staois have both sung his praises, but he is still clearly behind Stutzle, Tkachuk, Batherson, Sanderson, Chabot, Ullmark, probably Zub and Jensen, and arguably Pinto, (edit 2: Kleven), or Greig in terms of our most important players. He is in a similar position as Norris, except without the concern that he can be seriously hurt at any given moment.
Cozens is a good player, but he is also clearly one of our more expendable high-paid players. This team isnt a contender. If Cozens can be moved for someone like Cirelli, that is an obvious move to look into.
That said, I don't think anyone feels Cozens has worn out his welcome, doesn't have a future here, or is a problem. Only insecure Sabres fans who are desperate for anything to celebrate after their first three offseason moves are retaining their awful GM, retaining their awful coach, and hiring a homophobic meathead.
