Alfred Morris has said that the way he runs with the ball demands respect from his opponents.
Last year the running back broke the Washington Redskins' franchise record for most rushing yards in a single season, with 1,613 yards in his rookie season.
The 24-year-old told NFL.com: "I call it demanding my respect, the way I run. I'm not a [sledgehammer], but I will lower my shoulder on guys. I demand my respect.
"Then it makes it that much easier to just avoid [tackles from defensive players], or lose them and get around them, because now they're thinking he's gonna run me over."
Morris scored 13 touchdowns for the Redskins in 2012.
