"That's who Dak is. Rookie, fourth-round pick, in May or August, he's third on the depth chart. You don't get where he's gotten in his career, probably started way before he got here, by worrying about anything that's being said on the outside," Witten said. "He plays that way, he has that confidence with us, communicating, veterans, rookies, everyone in between. I think that's why he has the respect he has in this locker room."
