"One of the nicest things about NBC is that Tom Brokaw is not Dan Rather"

In this quote, Michael Gartner is expressing his gratitude for the news network NBC and its anchor, Tom Brokaw. He contrasts Brokaw with another popular news anchor, Dan Rather, and implies that Brokaw is a much better suitable for NBC. Gartner's use of the word "nicest" suggests that he sees Brokaw as a favorable aspect of the network. By specifying that Brokaw is "not Dan Rather," Gartner is also indirectly commenting on Rather's credibility and perhaps suggesting that he is not as favored or appreciated as Brokaw. In general, Gartner's quote highlights the value of having a strong and favored anchor for a news network.
