Earlier this week Football Outsiders put out a list of the league leaders in broken tackles among running backs. Here is how FO defines a broken tackle:

We defined a "broken tackle" as one of two events: either the ballcarrier escapes from the grasp of the defender, or the defender is in good position for a tackle but the ballcarrier jukes him out of his shoes. If the ballcarrier sped by a slow defender who dived and missed, that didn't count as a broken tackle.

Chris Johnson ranked second in the league among running backs with at least 20 broken tackles behind only Arian Foster of the Texans.  CJ broke 41 tackles on 360 touches (11.4%)  Foster broke 45 on 393 (11.5%).

Gramsey wanted me to point out that LeGarrette Blount, who you might remember was released by the Titans right before the season in hopes of sneaking him to the practice squad, broke a tackle 16% of the time he touched the ball.
