Just want to add my 2¢ about West Coast vs other announcers.
The characterization that West Coast announcers are not homers seems right. I think it’s largely dictated by the audience, many of whom are originally from other parts of the country and have conflicted rooting interests. An announcer being too much of a homer doesn’t play very well out here. One piece of anectdotal evidence (which you may have heard before): back in the 70s Harry Carey (yes, that Harry Carey) spent one and only one season as the announcer for the A’s. Didn’t work out; nobody like him. Too much a homer. He wound up back in Chicago, and it all worked great for him, but that shit just didn’t play around here.
Today in the Bay Area, we have a lot of announcers who clearly are a part of the organization, but they don’t let that get in the way of acknowledging and recognizing what the other team is doing on the field. Bill King always called a great game for the A’s, always hit the right note of excitement when Oakland made the big play, but he also gave the other team its due. And he would criticize the A’s when they were screwing up, too. (An aside: King was legendary for his brutal treatment of the umpires. Not so much if the A’s weren’t getting calls, but just if the umps were missing too many calls either way. Some of his funniest moments were rants about the umpires.) His style was just right for the Oakland broadcasts, and fit the West Coast mold in general very well. Ken Korach is excellent, in much the same way (though not quite as colorful). Vince Cotroneo seems to be doing a good job fitting in, too, with that same style: understated and as unbiased as can be expected. (Can’t talk about the A’s TV announcers, since I watch with the sound off and listen to the radio broadcasts. I just know the TV side is not worth hearing.)
Jon Miller has been discussed above, and is so widely heard that there’s not much more to say. Kruk and Kuip also do a great job for the Giants. Again, they’re part of the organization, but they don’t let it get in the way of recognizing when the other team makes the play.
I think Vin Scully is unique because of his Brooklyn origins, and the fact that he’s been with the Dodgers for so long. He really doesn’t have to be a homer–he can say what he damn well pleases, because he’s untouchable.
The one real upshot of the West Coast style is, when you are used to listening to those announcers, then get exposed to announcers from around the country, the other guys seem really grating. I get WGN on my cable system, but I can’t watch Sox games, because the announcers (especially Harrleson) really get on my nerves.
And I second the motion to get rid of Joe Morgan. “Gee, Joe, thanks for describing exactly what we saw with our own eyes in that replay. Care to tell us what color the grass is? Great analysis there, Joe.” It’s sometimes almost funny, because there are times when Miller will say something and Morgan will totally miss his point, and you can hear the awkwardness in the ensuing moment of silence. Jon deserves a better partner, but he seems to be stuck with Morgan.
