Defensively, Baylor's front line has some punch. They're not world beaters, but they can stop a runner between the tackles.
I say that because Baylor's secondary is hopeless. Once the ball is past the LOS, you can run freely wherever you'd like. Youth, injury, whatever, they just lack the cohesion to handle next level stuff like recognizing alignments, rotating assignments, and disguising coverage. They pretend one thing, then show their hand a full 5 seconds before the ball is snapped.
If Colin Johnson has indeed been working on his physicality on the line, Saturday could be a career day for him.
All this is predicated, of course, on the Texas OL being able to present even token resistance - no sure thing.
