When you’re a reporter, you’re supposed to keep fandom to yourself. Cheering (and, sadly, beer) is frowned upon in sporting-arena press boxes. There’s never a sign telling you not to; you’re just supposed to know, much the same as no sign tells you to wear pants in public. It’s okay to be breathless in your description of high sports drama, so long as the excitement is not tied to one side in the contest. And you’re not supposed to fawn over the competitors (a dictum many of ESPN’s reporters and commentators seem to have lain aside, but I digress).
