When CBS announces its fall sked on Wednesday, Les Moonves and Co. are expected to add five new shows, including family comedies starring sitcom greats John Goodman and Jason Alexander. Also in the mix: Clubhouse, a coming-of-age story about a 15-year-old batboy for the New York Yankees, and Dr. Vegas, an hourlong drama starring Rob Lowe as — you guessed it — a Las Vegas casino doc.
