I think it will be the same thing UT has been doing all season so far.
Throwing the ball at the sidelines, and handing it off when they have the numbers. Occasional deep pass that will fall incomplete, couple of mid range cannon shots, half dropped.
Defense will apply as much pressure on the QB as possible to help a vulnerable secondary. With the pressure they’ll have opportunities to stop the run in the backfield, which they have done really well, but if a back does get out it will be a big gain (again secondary).
UT will get screwed on some calls, will go for it on 4th when they probably should kick a FG, and go into the locker room with 2 or 3 timeouts.
I do think UT can beat A&M, but they are better than USC. It will be a tough game.
