That Bartman thing was blown out of proportion by local and national media. No one with a functioning brain blamed him for the loss within 24 hours of the game. I listen to a lot of sports talk and the calls to the stations at the time bore that out.
There are Cubs fans still bragging a decade later how they tried to assault him at the game and were only foiled by security.
You have Scott Turow still blaming him publicly.
The guy had to go into hiding.
Even the baseball in question was bizarrely fetishized.
All in all a very poor showing - though I'm certain you're right, that most people came to their senses after a few days.
The Cubs themselves played a very nice game against a very good team last night.
The Cardinals should be worried.
