Consider there are infinite parallel universes, in at least one of those universes Terry Pegula doesn't strike it rich in the gas industry and the Bills and Sabres no longer exist. I'm glad we don't live in that universe.
That said, I think the Sean McDermott hire is a step in the right direction (well firing Rex anyway), and the Sabres are on the upswing and will get better over the next few seasons as their core matures and guys like Gionta, Moulson (can't believe I'm saying this), and Franson are replaced with guys like Nylander, Bailey and Guhle adding much needed speed to the lineup.
It's difficult to be patient with either franchise after all the pain and suffering, but we have no choice at this point.
