They do a great job. They basically replay the fight's highlights with commentary. I highly recommend checking it out if you have ESPN plus.
At the end of the fight Dustin walked over to talk a little trash. Herb wanted him to chill and Dustin was nah, Fuck that. He's like you're going to smash face right? "Don't count those chickens, you want Justin next, right?"
They were both good sports at the end, though.
