It was an awesome showing, I agree. But then again, my hypothesis is that most out-of-towners needed to make ticket and travel arrangements well in advance, at a time when the Bills actually looked like an NFL team. I know I made my arrangements back around the time of our last win some six or seven weeks ago. Would I have still traveled and gone to the game if the Bills stunk back then like they do now? Hard to say. I'm sure many would not have.
On the less pessimistic side, Bills fans are the most dedicated and unashamed fans out there, so I bet it still would have been a decent showing regardless -- just maybe not quite as impressive.
