I know he had Sunday Nigh Baseball on TV, but Miller primarily (only?) did radio here, no? He's my favorite O's broadcaster ever, listening to him on the radio at night is a big part of why I fell in love with baseball. But was thinking of Brown as the best TV guy. Thompson I know did both, but he was mostly before my time. I only recall a few sporadic TV or radio broadcasts from him, he was more of an emeritus at that point than a regular voice.
Miller did some very limited TV work. Mostly radio. He's the best for me.
We've been blessed overall I think.. even the guys I haven't particularly cared for, were very professional and I think better than most.
