I like Joe Rogan and I think he does a good job. Honestly ,when I'm watching a fight I'm not paying too much atention to the commentators unless they really say something stupid. I really believe Rogan is a MMA fan, if he was'nt calling the fight he would probably be in the audience. Jim Brown was a great football player and a tough guy for sure but he did'nt know jack squat about MMA and it showed. Mike Goldberg sounds silly for sure but it is'nt his choice to plug TV shows thats just business, there will always be someone in that role.
