Can''t deny the chemistry between Handel and Petros, but as an avid listener to the show, I would like to see Petros as an addition rather than replacement. Handel doesn't care for sports in general discussion, Mirotta does a great sport segment in the news (entertaining and accessible to non-sports types) and Rich's political commentary and POV would be greatly missed. Don't get the impression Handel dislikes Rich, either.
Hearing Bill Carroll subbing for Handel this week, I now understand what Robin saw in him. He's not Handel, but doesn't need to be. I find him entertaining in his own way and he's able to better show it in the morning format. He's clearly the best sub KFI has had for Handel, IMHO.
I suspect both Bill Carroll and Petros will gradually become more a part of the show; until Bill Handel has had his fill of LA (his girls are teenagers, so I'm guessing 3-5 years), Mr Carroll along with Mr Petros pretty much seamlessly take over the show, with Rich Mirotta fully retiring and maybe serving as a political expert when warranted. If this is the plan, KFI has made a good investment in Bill Carroll and integrating Petros.
