You are correct, FSR will never be ESPN. They definitely should add more personalities and brand themselves in the direction of more personality driven Sports Radio! At least they would be a more entertaining network to listen to!
I hear too much personality on FOX or should I say "guy talk". It kind of reminds me of the failed FREE FM stations. ESPN has serious discussions about sports and the current games. FOX often goes way off topic.
I tried to listen to FOX sports today. These were the first (and last) three words I heard ..."Clint Eastwood Brah". That's what's wrong with FOX. There is NBA and NHL playoffs and a full slate of MLB. Instead they talk about Clint Eastwood. Plus I don't like guys who say "bro" or "brah" whether it's on the radio or (especially) IRL. Guys that use those words are questing for dominance and are unpleasent to listen to or be around.
