Watch: McCaffrey breaks Kuechly's ankles running route at practice

If Luke Kuechly can't cover Christian McCaffrey, the rest of the NFL's linebackers should be terrified.

The Carolina Panthers' rookie running back put Kuechly - arguably the best coverage linebacker in the NFL - on skates at practice while running a route.

McCaffrey showcased his otherworldly agility by beating the linebacker to the outside, stopping on a dime, and exploding away while evading his teammate again.
