That spinning kick has a lot of power behind it.Joe is one of the most knowledgeable non-fighters commentators in mma.
Record yourself (or anyone) for 4 hours straight every few weeks, for a decade. You will hear some of the dumbest shit you've ever heard.
All the fighters who commentate say a lot of wrong shit too. Look at Kenny Florian. For a guy who fancied himself a striker, his striking commentary is terrible.
