Ravens running back Ray Rice had a streak of 405 touches without a fumble ended by Steelers safety Ryan Clark in last year's playoffs—Rice allowed the ball to slip away from his body as he cut upfield, a common mistake, and Clark poked the ball loose while stretching to grab Rice around the waist. You'd think a runner's priority would be to stay upright, but Rice often finds himself fighting to get on the ground against a stripping, gang-tackling defense. "I'm a little guy," says Rice, who is 5' 8" but a powerful 212 pounds. "They just hold me up and hold me up and try to tear the ball out. It's not fun."
