I watch these guys most mornings. @JimmyNoodles got it right.
Simms rarely disagrees but is not chastised when he does. He's even tempered and takes alot of abuse with good humor. And he's pretty good at rating players.
Florio (originally a litigation lawyer) uses his courtroom tactics (loud, forcefull, loquacious) to make his point (even when he's just talking to himself like last Friday when Charean didn't show up). He concentrates on the business side of things.
But they are real, not rehearsed. Start with a list of topics and get as far as time allows.
