Just throwing my hat in the ring...
To my eye, Wolford is significantly better than Perkins. Yes, Perkins has elite run skills. It's a joy to watch him run around out there. But his throws are just freaking ugly. I have never once seen one of Perkins' throws and thought, "Wow". And I've seen several wounded ducks and a few awful throws (including his first two attempts last night).
Wolford throws darts out there. And his mobility is excellent, though not as good as Perkins.
My main concern with Perkins would be how he could be shut down if an NFL defense schemed a game plan against him. The book would be, "Perkins wants to beat you with his legs and short dump-off passes, so make him beat you with his arm."
I have never seen Perkins throw a rope on a 20 yard pass, it's just not a part of his game.
