I don't believe this about 92.5 for a second. NO WAY is CBS gonna invest in building a News/Talk FM from scratch. If anyone is gonna do News/Talk on the FM it's gonna be WFLA on 100.7 or 97.9. Now, if you were to tell me they're gonna flip either 92 or 94 to an adult CHR like RMarino has suggested, I'd bite... but I as well see that happening on 94 before 92 anyway.
As far as sports with a shift of the talent from 1010... possible, but they just don't have the rights or network affiliations to make it work. Without ESPN, FOX, or any of the local teams to lean on, it would be a very expensive endeavor and one they're probably not gonna embark on a prime signal like 94.1.
