Dallas Cowboys site writer David Helman on how the team will use OTAs to evaluate the RB corps:
"Ever since the draft ended, we’ve heard the Cowboys say that they aren’t ruling out the possibility of adding another running back before the season. If I had to take an educated guess, I’d say they’re going to use OTAs and minicamp to take a hard look at the guys on the roster. Those practices should give them a better idea of how well they can handle it. If they aren’t confident in those four by the end of OTAs, I bet they’ll go add another guy this summer."
This is just a reminder not to fall in love with any of the current backs (Darren McFadden, Joseph Randle, Lance Dunbar or Ryan Williams) as a clear-cut featured back. The team could pony up and trade for Adrian Peterson or sign a street free agent like Ray Rice or Chris Johnson.
