I think he's done okay. There are times however when he makes it a point to predict QB play calling based on defensive schemes and a couple of times it's blown up in his face when the QB has adjusted the play scheme or called an audible.
Just seems like sometimes that he's trying too hard to predict what is going to happen, as opposed to just letting the plays transpire and then offer insight after the fact based on what actually happened.
Surprised that he's still in the booth and not being wooed by Green Bay (or Miami) actually. Then again, it's the easiest money he'll ever make. So who could really blame him for taking the easier gig at this stage of his life...
