Here are fumble rates for NFL Draft running back prospects

Vision. Balance. Burst. These are the main traits scouts want to see from running backs. Ball security is also a crucial characteristic that is key to the NFL transition. The average fumble rate for the top 10 rushers in the NFL last season was one for every 124.5 offensive touches. Kansas City Chiefs rookie running back Kareem Hunt had elite ball security at Toledo (fumble rate of 856.0), and that skill translated as a first-year NFL player, as he fumbled only once in 325 offensive touches in 2017. Cincinnati Bengals rookie Joe Mixon had fumbling issues in college, putting the ball on the ground once every 73.0 offensive touches at Oklahoma. And that stayed true in his first year as a pro, posting a 69.3 rumble rate last season.
