The state of Texas has so many football camps and such available to youngsters growing up that talent arriving in college is perfectly adept at reading a defense and knowing where to go. Sark prefers this sort of mental QB who wins the play pre-snap. If you don't do anything about it, both the receiver and the QB know how to attack the defense before the play starts.
This works perfectly if nothing is thrown off schedule. With a clean pocket, the QB steps up, executes his mechanics, and puts the ball in a spot on time. it makes it look easy.
Of course, the defense is trying to stop this. The most direct way is to disrupt the whole thing by making the QB reset and play off-schedule. This is where Texas has fallen woefully short for over a decade.
If you're Boise State or something, you might need to get creative with blocking schemes, shifting power, etc. Sark and Flood figure there's no reason why a school like Texas shouldn't be able to go the direct route. Recruit and train big, strong bastards that simply win the fight with the guy in front of them. If you have your choice, that's the way to go.
That said, those gorillas have to learn a ton of footwork, hand placement, and other technique.
