Major League Baseball's many homer announcers fall into two rough categories: good and bad.
Enlightening, I know.
As always there is plenty of grey area in between, but that's the basic idea.
The good embrace you with their homerism and bring you into a shared space, where the blurred lines between observer and fan provide a sort of rhetorical comfort food.
The bad alienate you, either by abrasion or palpable insincerity.
Really, this is an extended disclaimer. Don't expect good or bad announcers on this list. Expect both, with a slippery shared trait binding them.
