"People get on me when I say this, but it’s kind of that first step toward the path of the Red Sox fan," said Grant Brisbee, 33, the editor of The McCovey Chronicles, a Web site for Giants fans. "You get a little cocky, a little arrogant. And they say, ‘No, no, no, Giants fans aren’t like that.’ But they’re not that far away from getting that really obnoxious national fan base." (Just like Yankees fans, Mr. Brisbee added.)
