at safety, the already solid running core, and if they were going to add a guy to play both sides the promise to Warner to get a shot this year from the outside looking in makes more sense, if not over Hadley since he is a bigger body than most of the other HB, and why I'm assuming they're trying it out, at least Warner over Dye with lack of slot experience, and his natural fit (as long as they aren't going jet sweep every time he's in there).
Granted that outside looking in spot isn't a great place to justify decisions from, and I like what the coaches are doing wth experimenting with moving guys around. It just seems a little more logical to have a few guys at HB before him
