Local Sports Talk Radio

Regarding a local AM sports talk station here: I wonder if you subtract time for every commercial ran, every plug given during shows at the stranges times for sauages, power bracelets, bat companies, TV's and Electronics, from an 11 hour local sports timeframe per day, how much time is actually spent talking sports? Maybe four hours? And if you subract how many times we have to listen to the guy from Plaquemine who can't talk but thinks he needs his own show, we are down in the one hour range I think. I mean when you have Zack Mettenberger on your show and one of the questions the host asks is if he loves Manda Sausages I think it past the point of absurd. Thoughts?
