UFC knows that commentating is a tied to the marketing of their sport. as much as I dislike Joe Rogan he does an excellent job explaining techniques, strategies, and delivering excitement as the color man. HBO COULD do that, but Merchant is cynical as hell, Lampley is half crazy, Kellerman has not found himself yet (they don't know if he's an analyst or color man), and half the boxers they have call the fights are always comparing what's going on in the ring to what THEY did in the ring, which would be ok if they weren't constantly spouting off with a tone akin to "Yeah, I was better than both of those chumps in the ring"
