I usually prefer Sky or Sho and I really like Tarver as a commentator. HBO is getting nauseating. RJ is cool but he often likes to get into arguments with the other commentators during a fight and steal the action - that's not his job as a commentator. Wasn't that one of the reasons why HBO silently left Foreman out of future fights?
Hopkins could actually be cool too with his insight but I sense the same thing will happen like RJ and Foreman.
