If the swing is purely rotational, then why do most hitters back foot jump off the ground or get drug forward at or just before the point of contact! There is no such thing as a purely rotational force. Rotation is created by a linear movement that has an axis. For example, a tetherball doesn't rotate around it's pole until it is hit forward by someone and then it only rotates because it is connected to it's axis (the pole) by a string. There must be linear weight shift to maximize the torque that occurs when the front heel sets down.
