Here's my take fwiw.
Aside from Kane, I didn't expect any big swings in UFA at F. There seems to be zero appetite to get into any deals beyond 2024/25 there. That immediately takes you off of most UFA lists (not that the Sabres would even be on them in the first place).
Adam's 'flex' plan for filling in the top 6/9 is (1) improve through a trade if possible, (2) adding one more prospect to the roster, probably Savoie or Kulich, and (3) in the case of injury, Zucher being bale to fill in on any of the top 3 lines.
Their center position still has huge question marks with Krebs in the mix and hoping that Thompson/Cozens will return to 2022/23 production.
My patience is running thin, and while I didn't expect him to be able to remake this roster through big UFA signings, it does seem like with Adams, what you see is what you get.
He needs to make a trade to address either the 3C or add something to the top 6.
