Why change the rules to help the offense?

That is not logical. The offense already has a huge advantage because they know what they are going to try to do, and the defense does not. The defense has to react. Granted, defenses can be pro-active, such as pressing, but the unfolding of the play is in the hands of the offense. The defense has to identify and react to the offense. It is sort of like saying that the bad-guy gunfighter that draws first has the advantage because he will draw first, while the good-guy gunfighter has to react when he begins his draw. The NCAA's recent reactions are like saying that the good-guy has to count to three after he sees the other guy begin his draw. Let's make sure the good guy gets killed.
