Mike Gorman is easily my favorite. When I first heard Johnny Most I hated him....by the end of the third game I heard him announce, I loved him....my favorite all time. Tommy, the same...hated him at first, but loved him quickly. Guess it is because I am a "secret" homer, too. I don't want to be impartial. I still miss Bob Cousy...despite being a Celtic legend, he is not really a homer.
Hate Marv Albert, but that may be unfair..it may be because of all his baggage...
(Oh, and I used to secretly get a kick out of Howard Cossel, too, but at the time I wouldn't admit it.)
