The Longhorns have two kicker/punters on roster: Justin Tucker, a senior, and William Russ, a redshirt freshman. Texas also has a fairly deep stable of return men, from juniors Marquise Goodwin and D.J. Monroe to sophomore Darius White and incoming freshmen like Quandre Diggs, Mykkele Thompson and Jaxon Shipley.
The Longhorns don't NEED a kicker or punter, per se. They might be best off taking an extra walk-on at the position to provide some depth in case Russ doesn't work out, for whatever reason. As far as return men go, it would be nice to add another couple of bodies to that rotation, as it is in any class.
Texas hasn't spent, and likely won't spend, any scholarships on pure special teams players. But the Longhorns have grabbed some players, like Thomas Johnson, Orlando Thomas and Johnathan Gray, who have some return ability. Adding another player in that vein, like a Kendall Sanders, would only help more.
The Longhorns haven't spent any scholarships on special teams only players, so the grade above is based on landing several players with return potential, in addition to their skill position talents. When added with the crop of returners in the 2011 class, the Longhorns have built a nice young group of return-capable players.
