FRISCO -- Two years ago former Cowboys running back Joseph Randle made headlines when he said DeMarco Murray left a lot of meat on the bone during the previous season.

Murray was coming off a year when he rushed for a franchise record 1,845 yards.

What more could Murray have done?

Well, Ezekiel Elliott made a similar statement about his own impressive rushing season on Wednesday.

Despite winning the rushing title as a rookie, Elliott said he "left a lot of yards on the field" in 2016.

In 15 games, Elliott totaled 1,631 yards and 15 touchdowns on 322 carries. No other running back was within 300 yards of his total.

But when he watches film, last year's fourth overall pick sees opportunities to make an extra defender miss, possibly turning a 30-yard run into a 50-yard touchdown.

"I think there is big room for improvement," Elliott said. "Just being more comfortable, being able to anticipate more. That's what I'm working on this offseason."
