But Elliott hasn't spent much time reflecting on his accomplishment.
He still has work to do.
His 1,631 yards, 322 carries and 5.1-yard average from the regular season mean nothing going into the playoffs.
Elliott understands that more than most because his gaudy college credentials meant nothing when he arrived in the NFL. He gained 51 yards on 20 carries without a run longer than 8 yards in his debut against the New York Giants.
"I wasn't comfortable in the system," Elliott said. "Now, I feel completely comfortable."
The next week he fumbled twice, losing one, and was benched for the final six minutes as the Cowboys rallied to beat the Washington Redskins.
In the next four games, he gained 140, 138, 134 and 157 yards to seize control of the NFL rushing lead.
"It definitely means a lot to come in and accomplish that my rookie season," Elliott said when asked what the rushing title means to him.
"But I just have to thank all the guys around me. I have a lot of great pieces around me that helped me accomplish it, including the best O-line in football."
