Tom Green has been on the air in Denver for more than 25 years — an impressive record in a shrinking industry that's buffeted by the changing marketing winds. But Green's low-key delivery, easy style and quick one-liners remain a constant, and he's stayed a pro — whether he's doing sports for channels 9, 7 or 31, or news on Channel 2, where he currently leads the station's morning show. With or without a tie, Green is a survivor. Let's hope he stays that way.
