David Gregory Wasn’t the Real Problem with NBC’s ‘Meet the Press’ | Variety: "Even Gregory’s harshest critics should have some sympathy for the guy. He had some bumps in the road but for the most part proved himself just as tough an interviewer as his peerless predecessor, Tim Russert. Perhaps Russert was really the problem here: When a legend casts a shadow that long, no one underneath it really has a shot at shining through.

I don't think this is true. The problem was Gregory didn't have bona fides with conservatives. Although Russert was liberal, conservatives trusted him to ask tough questions from their perspective. Also he was a jolly fellow. In contrast, I will always remember David Gregory as the guy in the White House press room whining about how Scott McClellan wasn't really answering questions.
