The most intelligent thing for Dallas to do would be to forgo this random opportunity to trade for Adrian Peterson, and opt to draft a back -- even two -- in this year's NFL Draft. Because this year's class is sickeningly good.
Don't give up a pick you'd use on one of these potentially talented backs to get a 30-year-old runner who will cost you double-digit million dollars. Don't do it, Dallas. It makes no sense.
