Why not

Would you be willing to swap Bryson with a different prospect? We have a lot of LHD in the system; how about Ostlund or Rosen?

Outside that I think it works best for both sides

No. Who are we competing against for Gibson? He's asked out and the goalie market played out

Asking for ostlund or Rosen changes the deal considerably. Bryson is undersized and frankly there's a good chance he gets waived, and clears waivers. He was not good at all last year, but it could be the system, we don't have one. To follow up on that, ostlund and rosen were mid first round picks that are progressing as you would hope, I can see asking to swap for rousek or Murray, or one of our Russian forward prospects, but ostlund and rosen would significantly increase the value.

I think the Ducks would ask for at least a B prospects. Ducks could always throw a pick if they up the prospect

Gibson has become the new shiny toy for Sabre fans to covet.
30 yo Gibson with a $6,400,000 AVV until 2027 (UFA) had a 3.99GAA, 14 wins 31 loses 8 ties and a 0.899 SV%
24 yo Luukkonen with a $837,500 AVV until 2024 (RFA) had a 3.58GAA 17 wins 11 loses 4 ties and a 0.892 SV%
How much is john going to upgrade the Sabres between the pipes?
Take out Bryson, Luukkonen, the 2nd and I would still say no.
Well that is my take.
