This is a quote out of a Mike Epstein article on linear versus rotational:

"one shared movement is a weight transfer. The exact definition of linear hitting is the weight begins coming forward in the stride and continues coming forward through contact and follow-through. In other
words, the hitter’s weight is one continuous movement towards the oncoming pitch. A FLEXED front knee allows this continuous forward
movement to take place. In rotational hitting, there is also a weight transfer forward in the stride, but once the front heel drops to trigger the swing, the front side is blocked by a RIGID front leg,
and the hitter’s linear movement becomes rotational. Body momentum at this point revolves around a stationary axis, preventing lunging"

This is what Yeager also teaches which in my opinion makes him more rotational than linear. However, Yeager is not an advocate of staying back.
