I think most get use to their hometown guy and compare and don't always care or see the big deal when others rave about a Scully or a Harwell or any of the real big names....I liked Jack Buck a lot though when I did hear his games.
When I first heard Ernie Harwell call a game , its been many years ago now...I couldn't believe how bad he was...and I wondered what anyone saw in his announcing skills...it really comes down to what you're use to.
Chuck Thompson , who is in the MLB broadcasting wing of the HOF was our guy, he called many big games for the etworks in the early days of sports on TV, as well as the Balto Colts and of course the Orioles...
Bob Uecker (Brewers) is another one that has a really odd style that you either love or hate.
