I agree with 99% of what the OP said.
I, too, have been a fan since 1970. My father took me to games to see the French Connection, etc., and it was a team you could have pride following. There was a connection with the city and fans. That is all lost and seems nothing like what we experienced back then.
I truly believe is has to do with management and leadership. The Bills are successful because they found Beane and McDermott. From there they built a team we can believe in. They brought in players with the right character. Doesn’t everyone feel Josh is a “Buffalo guy”? His work ethic and personality (don’t tell me when he jumped over a linebacker you didn’t jump out of your seat) fit the team and city perfectly.
The Pegulas need to find the hockey equivalent of Beane and McDermott. That’s on them 100%. If they do, the posts here will change quickly. Until them, they deserve the criticism they are receiving by fans.
