I'd like to think my posts, when taken together, reflect my history of watching Texas/oSu. The Cowboys usually don't have Texas' caliber of athletes across the board. They just manage to use that one special talent so effectively that it throws all the advantages Texas has out the window.
This should be a game where the Cowboys complete some longer passes to a talented receiver, have some yards by a determined RB, but ultimately find themselves bogging in FG range while giving up TDs to a versatile Texas offense. What could easily happen, though, is the Texas defense gets jittery after the WR and RB get off a couple of talented plays. Then, they start over-correcting - which leads to busted assignments. Instead of giving up a couple of 1st downs and a punt, they give up 60 yard instant TDs. The Texas offense feels the pressure to compete point for point, someone presses too hard, and turns the ball over. At the end of the game, Texas is hoping to grab an onside kick for a final gasp at the tying points.
I believe this Texas team is tough - in the materials engineering sense. A material can be strong. Glass is strong, but ultimately fails because its brittle. One crack propagates through the entire material and makes it fail. Steel, properly made, becomes tough. It becomes tough when its inherent strength is reinforced by being beat on. Cracks form, get heated and sealed, and it gets beat on again. Through this process, the material becomes able to flex and give. A small crack is prevented from causing the entire material to fail because it is intercepted by more of the material.
oSu possesses the capability to defeat Texas, but only if Texas helps. I believe this Texas team, in addition to being talented and capable, has learned to be tough when the cracks occur - only because they've been beaten on in years' past.
