Basically, you evaluate the three/two stars out there every year (Which you should be doing anyway). You find some kids who are under the radar for whatever reason, and make them an offer. They can be a preferred walk on, meaning their spot is assured, or a walk on and have to keep earning it.
A kid like Ronnie Larue (
http://rivals.yahoo.com/footballrecruiting/football/recruiting/player-Ronnie-Larue-137902) is the perfect example of what we should be doing. He's a baller, kid has several FCS offers, but naturally he wants more and is hungry to prove it. You find two or three kids like this and offer them the opportunity to come to Texas and prove they belong.
Larue does this (he won't here, not a UT fan) at the FBS level and I think he'll more than earn a scholarship. Kids like him should have those slots.
