People go online to get fantasy sports info & sports gambling odds. They don't listen to a cadre of blabbermouths on the radio (especially on a crackly AM station with old person stench) hoping to come across a topic of interest.
Again, SiriusXM has a staffed, in-house fantasy sports channel and has had one for some time. There's interest out there. It may not be enough to move the meter ratings-wise, but anyone who listens to "blabbermouths" offering tips on cashing bets is a potential customer for that channel or station's advertisers, much the same as listeners to the "blabbermouths" on Bloomberg Radio are for advertisers offering tips on successful "investing," as gambling is known in the financial world. No one is listening to this stuff for light entertainment; they're all out to make some money.
