My attitude re. Dunn is, if we get him, cool. If not, I won't be too disappointed.
Why? I'm really, really excited about Thomas Rawls. I think he could be a lot better than the 3 star rating he was given by the recruiting services.
Could be a toss-up whether we'll see him this year though..... There are like 6 other tailbacks on the roster... although I think I recall hearing the coaches aren't real enthused about any of the backs we have, and are excited about Rawls' potential.
IMO Rawls is one of the most important players to keep an eye on in camp. If we hear good things about him, could mean he's ready to be a contributor, if not, could mean he's headed for a redshirt.
I'm not an expert at evaluating football talent, but, my reaction to that video above is that he could be a really exciting player.
