Or maybe it's just that your ideas are too outlandish even for people who would be prepared to sell...
There is nothing coming from Sabres fans that is irrational about their plaxyers.
Buffalo has zero reason to trade the best of their (youngish) etablished players, because they are the part that is working, the part they need more of, not less. They also have zero reason to part with veteran players for picks and prospects, because they already have those coming out of their ears and need more good veteran players, not less.
Buffalo fans seem to be more than willing to give up on some high-end prospects to improve their team, Just like they seem to be willing to trade some of their better players for players of equal skill that are a better fit to their needs, or UFAs to be for something they can actually use. Now, if you want to fleece them, they would obviously reject that. But that would make you the irrational one, not them.
