I think Mauro suffers from the three man booth. His role isnt clear. He's part play by play, part analyst. This hurts Frank too, because he splits his mic time with Mauro. They step on each other alot.
I think they should just go with Gus & Frank, and let Mauro/Quadros/Miletich handle the Challenger Series. The three man booth can work, but it has to be two clear cut analysts, not one play by play, one analyst, and one guy who's trying to do both.
