He's actually not that bad. Good ad libbing. Good body language if a bit stiff. And reacts to what he sees in the content. Good work for the local anchors there of keeping a straight-ish face as they soldier through their usual shifts. It's hard to catch when a famous actor tosses an ad-lib. I often teach my beginning students that they need to let each other know when they are going to toss an ad lib to their co anchors, so it doesn't fall flat and gives the co-anchors time to prepare a snappy comeback.
Newscasts are all about showing harmony among the crew (even if they hate each other in real life) because the audience expects this.
