Liufau is looking faster than he did as a rookie last season during the early part of training camp,
Patrik Walker of DallasCowboys.com reports. "That was a big thing that I wanted to work on this offseason, and also my conditioning," Liufau said this week. "Knowing [new defensive coordinator Matt] Eberflus' system, we're gonna be running a lot, and it emphasizes running through the ball, and so we got to be in the best shape to be able to dominate and play the kind of defense that we want."
