It's enough to have driven the passionate fan base to the edge.
"Is it frustrating? Yeah. Is it painful? Yeah, but difficult isn't the word I would put on it," said Jay Rosen, a season-ticket holder since 1987. "Sometimes you're more or less emotionally involved, I guess, as kind of a self-preservation mechanism. So you find something else to do on Sunday rather than watch."
Bad as they've been, Rosen would never give up on rooting for the Bills. He has contemplated cutting back his financial commitment and canceling his two season tickets, which cost him about $1,500 a year.
Ever the optimist, Rosen re-ups every season in fear he might miss the team's long-awaited rising. It helps that he's become close with the people who sit in his section at the stadium. And that's comfort enough.
"You suffer together," Rosen said with a laugh. "Everybody has that in common. So yeah, you're not suffering alone in silence."
