Baurle strikes me as being a bit of a douche off air (he's definitely one on air), and he definitely has a huge ego. Bellavia probably didn't want to risk Baurle being an ass and have it tied to him.
I can't stand listening to that show anymore when Bellavia isn't on. Since their traffic reporting at 5pm skips the 10 after report I usually miss it, and I've found it's not that accurate for the 990/290 area even though they can literally look out the window of their offices and get a live view and not rely on delayed cameras, so I rarely even try to listen to their show anymore.
