Sisk, I bet the sky is Maroon in your world. But your biggest weakness, this is Earth. And on Earth, your university is a fringe top 25 program of all-time. USC is one of the top 3 programs of all time. They have more recruiting advantages than Texas does, the only thing they don't have more of is money, but then again neither do you.
If both schools were in prison, they would own the cell block and aggsy would be bending over grabbing ankles.
Now, Sumlin might want to stay in aggsyville and call a$m home for the rest of his life, but don't count on it. Your school is no different than USCe, Clemson, Georgia Tech, North Carolina, or Tennessee. When a big dog comes calling, your coach would be stupid to stay.
