Not as impressive.
Jones, Gore and Jackson ranked among the seven worst in the league for fumbles per rushing attempt (among players with more than 150 carries).

The Cardinals' Tim Hightower fumbled once in 143 attempts last season. Among runners with at least 100 carries, the Bengals' Chris Perry had the worst rate by far, fumbling five times in 104 attempts, or 4.8 percent of the time.
