It's a Pac back attack! Continuing with his look at the best NFL prospects by position in 2014, ESPN's Mel Kiper projects that four of the top 10 running backs hail from the Pac-12. Oregon's De'Anthony Thomas is No. 1, which is understandable, but also a little bit surprising simply because he doesn't fit into any one category. I could see traditionalists arguing this point. But Kiper strongly supports his claim.
