I believe The Babe has radio in her blood. She's like so many others. She gets sick of the drama in the business, so she leaves. But her love for radio in general comes back to the surface after being dormant for a while. It's like many other specialized professions. You begin to miss it after a while. Not all the drama, but the good people, the work itself, etc. I think this is the case with her.
I think a pairing with Brantley could go well if she runs the show and he provides the insight with his knowledge particularly in football in a complimentary fashion. Brantley being by himself, in spite of his knowledge, was just bad radio.
