I threw this together from the ESPN website.
Might give us a some insight of what to expect this Sunday from or running backs.
Keep in mind its preseason stuff, but its pretty much all we have to go on since they don't have many touches during the regular season.
I also did not put in the receptions they had, just the rushing attempts.
