In two games against the Philadelphia Eagles in 2012, Washington Redskins running back Alfred Morris ran the ball a total of 42 times and averaged a modest 4 yards-per-carry - down from his season average of 4.6.
In the first game, a 31-6 blowout win at FedEx field on November 18, Morris wasn't much of a factor.
He rushed for just 76 yards on 3.8 ypc, but Robert Griffin III carried the team to a win rushing for 84 yards.
Philadelphia had to stack the box to account for Griffin running, and this allowed him to complete 14 of 15 passes for 200 yards and 4 touchdowns.
The second game, a 27-20 win in Philadelphia on December 23, Morris played a bigger role.
He rushed for 91 yards and a touchdown (averaging 4.1 ypc), forcing the defense to stay honest.
This also allowed RGIII to make plays with his arm.
If Washington doesn't want to have to rely on Griffin carrying the ball 12 times in his first game back from off-season knee surgery, then Morris has to play like he did in the second game.
With pressure from everyone for Griffin to be more careful when he runs, the second-year quarterback will need to lean on his running game more than ever while he re-adjusts to the speed of the game.
It shouldn't take him more than a quarter or two to shake off any rust that he might have from being absent during the preseason, but that's all it may take for the new up-tempo Eagles offense to pull away.
Washington will have to pound the ball with Morris not only to take the pressure off of RGIII, but also to keep their defense rested.
If he's able to consistently gain four to five yards per carry and cause second-and-short and third-and-short situations, then Washington should walk away with a win.
If he struggles and the defense is unable to stop Philadelphia, RGIII will have tighter passing lanes and a full-out pass rush enticing him to tuck the ball away and run.
Not only would the game be at stake, but also the franchise quarterback.
