Has Cowboys QB Dak Prescott lost his mobility?

At the beginning of his career, Dak Prescott was considered a dual-threat quarterback. Now, the Dallas Cowboys star almost looks immobile.

After Prescott threw two interceptions in Sunday's 30-24 loss to the San Francisco 49ers, The Dallas Morning News' Tim Cowlishaw claimed the QB "can't run," which is his "biggest problem." 

"On the morning of the season opener in Cleveland, the Cowboys signed Dak to the biggest contract in NFL history, a $60M average per year price tag that will hold up for at least a few months and keep him in the top five most likely for years to come," wrote Cowlishaw. "But even if [owner] Jerry Jones paid him to be Dak The Immortal, Prescott has given the Cowboys Dak The Immobile."

Through his first seven starts, Prescott is averaging career lows in rushing attempts per game (1.4) and rushing yards per game (3.4). Additionally, he has been sacked 18 times, tied for the 10th most in the league.

It's unclear whether Prescott, 31, has lost some of his mobility or Dallas has convinced him not to run.

Per ESPN's Todd Archer, Jones said, "I think it's both" when asked whether Prescott doesn't want to run or can't Tuesday on KRLD-FM in Dallas. Jones then backtracked, saying Prescott can still run, but he wants him to avoid potential injuries.
