Are There any Standards in Sports Talk Radio?

Due to some radio difficulties in the Odds and Sods-mobile during our trip back to Detroit and our Ipod adapter going MIA, we were forced to put up with Detroit Sports Talk Radio. We were listening to the show, which we are about 90% sure was The Sports Inferno on 1270.
One of the analysts during the Monday show compared the Lions’ Sunday drubbing at the hands of the Philadelphia Eagles to “a failed abortion,” because the performance was “messy.”
First of all, how does that stuff pass the censors on radio. It’s obviously offensive to pretty much any human being, regardless of whether one is pro-choice or pro-life. It’s not exactly a catchphrase one could see Scott Van Pelt spouting on Sportscenter any time soon (assuming he doesn’t want to be fired). One can hardly see Mike and Mike dropping a dead fetus joke. Even Cowherd would probably find that comment too crude.
Second, why use that metaphor? Yes, the Lions performance was shockingly hideous and radio show hosts are prone to hyperbole. But, “a failed abortion?!?!?” It’s neither descriptive nor creative and it’s needlessly disgusting. There are endless numbers of analogies and adjectives that could be used to describe how bad the Lions are. Why that one?
