Let's give it up, finally, for the Big Dog, Joe Rose. The former Miami Dolphin wide receiver is as close to a Miami sports institution as we have at this time, at least since Dan Marino and Don Shula have retired. Hard to believe in a way. Rose hardly distinguished himself as an athlete. (His greatest claim to fame, which he'll gladly tell you about, is catching Marino's first touchdown pass.) But as a broadcaster Rose has developed into a welcome, humorous personality, the ex-jock with a soft spot for the underdog. In his appearances on WQAM, on WTVJ-TV (Channel 6), and hosting numerous charity roasts, Rose plays the doofus, willingly attracting abuse from his co-workers, especially his linemates on the First Team, WQAM's very listenable morning sports-talk show. Clearly, though, Rose is no idiot. Compared with other sports clowns, such as former Steeler QB Terry Bradshaw, we'll take the underdog every time.
