It's easy to find fault in any of the TV commentators on any given day, especially when we're not the ones attempting to express very specific thoughts about a particular race, driver, situation, etc. within a very short period of time while at the same time listening to producers and so forth constantly talking in our ears. Do they make mistakes and occasionally say some silly things? Sure they do, they're human. Still, they all generally do a fantastic job and if Fox Sports suddenly brought in a entirely new crew, we'd find things to complain about with them too.
I can say that in my 30 years of Navy air traffic control I've heard (and even said myself) some of the dumbest and silliest things you can possibly imagine... especially during my tour at Whiting Field - the USN & USMC's primary flight training facility. Student aviators are the best!
