Murray has had his first two seasons in the NFL hampered with injury and has not yet reached 1,000 yards in one term, but has confidence that he can make a big impact next time around.
"I think I'm capable of anything, [including 2,000 yards in a season]" Murray told the Dallas Morning News.
"We definitely need to emphasize the running game. When you're second to last in attempts, more than likely you're going to be second to last in rushing, so we definitely got to get the running game going."
Murray has totalled 1,560 yards in his first two years with the Cowboys.
