"Alot of people have been talking about I'm a frontrunner and I'm doing a great job and that's cool [because] I can kind of focus on what I have to do to stay there," Martinez said. "Now having to be a captain, it's cool, it's an honor but at the same time it's like, 'Am I ready for that?' I don't know if I'm ready for that."

Besides his wavering confidence with having to lead David Arquette, Kym Johnson, Nancy Grace and Tristan MacManus, the war hero turned actor is still a force to be reckoned with on the dance floor and his partner Karina Smirnoff hasn't allowed him to slow down with the mirror ball trophy within their grasp.
