I have to agree with you radiofree1, I have heard so many complaints from listeners about 620 NOT giving them what they want. These are passionate sports fans complaining, not the average dunderhead who finds what most of the hosts are offering-- completely unprepared, unthought-out garbage. The reason why 620 dominates has nothing to do with what they are doing now. It has much more to do with dominant signal strength and promotional budgets compared to 1010 and 1470 (maybe even combined). I also think 620 has been coasting on its legacy built up by people like Chris Thomas, Sandy Penner, and Tony Bruno a few years ago. As long as 1010 occasionally blips on the radar, and 1470 keeps missing the ratings pages, the management at 620 will accept whatever they get.
One more indication 620 isn't bringing the audience what they want: Despite the Rays playing great, the Lightning making all sorts of news, and people gearing up for Buc training camp, 620 delivered one of its worse spring books I can remember. There are too many better options for true sports fans (satellite, internet, blogs, etc.) than 620, and the people there should know that by now.
