"Have you ever heard Niner fan call in shows?"
When Barb was school superintendent in San Rafael we had a condo in Tiburon. I would fly up on Friday nights and fly back to So Cal Monday morning. This went on for 3 years. During football season I would listen to the Niner message boards and call in shows after a Sunday game as well as being connected to this board. The only thing that stood out for me was the Niner broadcasters on the radio for the games. Talk about homers ? Never any respect for the opposing teams and their players. Maybe that rubs off on the fans.
The absolute worse phone in fans I've ever experienced were those in New York. When either the Yankees or Jets or Giants were bad it was embarrassing bad for an out of towner like me to listen. They even made a movie of it: I think it may have been called "The Fan". This poor lonely guy whose life is solely about the Giants (football I think) has had enough so he sets out to murder the QB which I found to be a little below average.
