Rank these running backs

[BadBoyBenny]

I didn't think it was that disputed by anyone that certain things like holding the ball in your away from your body, or not switching arms properly when running down field, or not covering with both hands through the hole will increase the likelihood of a fumble. I also didn't think it would be disputed that certain running backs in the league do these things better than others, and that for a portion of his career Tiki Barber did not have good fundamentals in this regard, and that this was a cause for his high fumble rate.

Do you disagree with any of that?
