I would doubt any of the Genesis stations would go silent. Three AM signals in the 20th largest market aren't going to evaporate; they would be sold if the going REALLY got rough, I would bet. Especially when two of them have arguably decent daytime power.
I have asked on other posts HOW MUCH it really does cost to run a station, exclusive of the talent, and never got any kind of a ballpark figure from anyone. I would bet it can't be much if some of those AM Spanish language stations can afford to stay on year after year, as well as some of the religious stations. Therefore, I'd bet all three of these stations can't be costing too much to run, and they can afford what little local talent they do have on the air.
I've listened to WWBA and its not a bad alternative to regular talk radio. The interviews all come with a decided political slant, but at least the people opining to the hosts have some credentials behind them that a "Valrico Bob" does not. I think I heard a promo for what might be a local talk show at night, but the promo had something to do with "which of youse guys is watching porn?" - seemed pretty lame. I don't listen to WHBO too much as sportsradio is not my bag, but the Yankee PBP can't cost too much (maybe it pays them as many of the ads are straight off the New York homebase). If anybody was going to change format it might be them, as a distant number two sports talker in a three station race can't be too billable, I would bet. (Swing and jazz, anybody?) (Where is Les Forester?) I also don't listen too much to WMGG, although I did hear Capt America a couple of days ago, and it seemed that the people who heard him on 820 figured out how to tune into 1470. I think the rest of their day is satellite programming, which has to be pretty cheap to run. And despite the numerous comments about how lousy their signal is, I can hear it is Manatee County, albeit in my car, which is where most talk radio is heard, I would bet.
Would more local content help them all? Absolutely. A question to local radio professionals "on the beach;" if you were given the opportunity to get behind a mike for 30 - 40K a year, would you do it?
