Capefish, you always have some thoughtful ideas.
I think it's more likely 790 will go for the Fish before CC. CC would never go into any deal it loses money on. But it's not out of the question that 560 will push hard to keep the Marlins, just to keep it out of 790's hands. Beaseley is apparently okay with losing money on broadcast rights, looking at the added expense as "marketing." As much as Neil may bitch about them, and as much as Hank bad-mouths them, baseball - even the Marlins - is the best sport for radio, the one that actually brings ratings. It's also possible the Marlins, despite the negatives you mentioned with QAM, will stay put. It's been their consistent flagship from day one, they have a pretty good network established by QAM, which is still the dominant sports station, although by the slimmest of margins.
It will get interesting next year, when the HEAT deal opens up. Going to a station where they are not the dominant sport is unnacceptable to them, probably eliminating QAM from the competition. If 790 hangs on long enough, I'm sure they will make a try, but HEAT apparently love WIOD/CC.
The other wild card is Hurricane sports. QAM has treated them like %^%$(@#! Don't know when their deal is up. As for the Panthers, a non-entity. I don't think it costs QAM much and it flls up their night time schedule and the 'Cats are in no position to bargain.
