And Stewart knows better than most how it can work.
The last time a pair of backs on the same team topped 1,000 rushing yards in the same season was 2009 when he and DeAngelo Williams did it for the Panthers. They kept the team afloat that year as quarterback Jake Delhomme struggled through injuries in his final season with the team.
Stewart ran for 1,133 yards, Williams went for 1,117, and they managed to go 8-8 despite the instability at quarterback, part of a long run of rushing-focused offenses during those years. The team's success in those years was built on the run game, including their 12-4 record in 2008 when they ran for 2,437 yards (Williams had 1,515, Stewart 836).
But more than the yards, it was the personality that a strong running game offered, knowing the Panthers had a pair of backs who could break long runs or simply keep the chains moving, and that took a cumulative toll on defenses. Stewart might have been the bigger one, but both were hard to bring down.
