Rachel Nichols: Unguarded will air Fridays at 10:30 p.m. starting Sept. 20. CNN hired Nichols away from ESPN to anchor a weekend sports show. Nichols was one of Zucker's first major hires when he took over the network, and he said the addition of a sports show was part of the network's shift towards a "more varied set of programs and reporting" at the time.
