Ok. I don't have a problem with that. But in the end you still trying to resist turning the upper half. If a player coils during their "load" and tries like hell to maintain the position of the upper half. You are going to create a lot of resistance and as the rear leg starts to turn it will start to pull the upper half around. Can you have more resistance by the tilt and sending the barrel rearward and even a pullback, sure.Most of the stretching is done prior to swing launch. The last bit of stretch is the barrel sent rearward as the lowerbody pulls the barrel forward. However, it’s the hands and back leg starting at the same time as you tilt that creates the final stretch.
Some players lower half opens a bit more first than others. IMO and i can be totally off base, not all players are going to have the upper and lower going at the same time.
Example pujols. In this clip. Look how long his name on the jersey stays stationary for quite a long period as his lower is turning before it starts getting pulled around.
Sho is another
Carlos - Notice by the way his hips have basically fully opened his barrel still back upper still back
