A rookie isn't going to have warts? I get what you're saying but I'm talking about something like a 1 year/$1M deal for someone like Ridley who will take a dirt cheap short-term deal to try and reestablish his value for free agency in 2016. Good rookie RBs can usually step in and play well but considering the Cowboys should not/do not trust Randle and clearly see Ryan Williams as nothing more than an emergency call-up, they could use an experienced vet to split carries and add quality depth. Ridley went for >1200 yards and 12 TDs a couple years ago. He has talent and could do well behind this OL. Why not bring him in if he can be signed for minimal money?
