Anthony White has just posted another NCAA Football 11 blog. This one covers the one back offense.
"Like the spread offense, a big point of emphasis for the one back offense is to control the number of defenders a defense can deploy to the box. As mentioned earlier, the one back offense is considered by many as the original spread offense. Many of the core principles of both systems are similar. As we pointed out with the spread offense, one back teams also want to use multiple receiver sets to spread the defense out. If the defense doesn't cover/align across from each receiver, the offense must be willing to throw the ball at any given point. This idea is known as "Throwing Uncovered". An offense that's willing to throw to an uncovered receiver at any given point on the field will force the defense to cover/align across from the offensive receivers."
