I think this drill actually takes away from what you are trying to accomplish. It's not *JUST* about a strong explosion from the drive leg. Game time pitching requires 2 feet on the plate and *BOTH* feet/legs need to get into proper position in order for an effective kinetic chain reaction to occur.
This drill is like only training half your body. I understand the idea, have used the drill myself, but no longer think it's valuable or effective. In fact, I think it could be counter-productive.
