Choosing the best TV anchor is tough, because even people in the TV business can't really tell you what makes a great anchor. They'll usually say ratings. But why is one anchor trusted and another not? It's called gravitas, and John McCaa has it. He communicates straight-on with authority that isn't stuffy or arrogant. We hear McCaa writes his own copy, but even when he has to wing it on breaking news, he's smooth. He's a master of the moment. That comes from years of experience, nerves of steel and solid news judgment. Once again, McCaa's the best anchor on our airwaves.
