FWIW an HF poster, the same one who said they heard back in July from a source that Calgary had something tabled with Buffalo and was waiting for the ask to drop, just wrote these posts:

From seeing their post history, also said a couple days ago that the Sabres ask from the Flames doesn't include anyone on the current Flames top line (Gaudreau, Lindholm, Tkachuk)
I don't know this poster or what their source is but just thought it was interesting and wondered if any CPers have heard anything similar. Still not getting my hopes up.
