Harry Doyle should replace Buck.
Back in the early 60s and before, it was common to select the lead sportscaster from each team to broadcast the Series. They worked alone and would alternate during the game.
Then some time along the line, the networks decided to use their own people.
They also decided to put two or three people in the booth. This might have been done to ensure that someone would always be talking. When a person works alone, he'll occasionally pause. To network bosses and sponsors, that's dead air. And dead air to them means that someone might change channels. Maybe I'm wrong, and if I am, I'll be corrected. But that's what I think.
Personally, I liked it when they worked alone because that meant they were talking to me and not to each other.
