Like most of the guys who posted above, the ring announcer is tied to the era in my mind so it varies. But unless I'm in the Ali era or later (Cosell), I'm always hearing Don Dunphy calling the blow-by-blow at ringside.
Since my interests, unis, and sims rarely go beyond the late 1970s, I don't think too much about broadcast media pre- or post-fight interviews or analysis. Typically, it's the print media guys in the dressing room after the fight for me.
But then I have Skip Bailey in my unis, so who could ask for anything more in terms of interviews or analysis?
