Is this for no stride hitters only or do you think this is for traditional strides as well?It all depends on how you define weight shift.... In my opinion this hitter is not starting in the launch position. You can see his hips move towards the pitcher before he launches. It isn't until his hips stop moving in that direction that launch position is truly reached. When the launch occurs, he does have some weight applied at the front foot, but there is more weight applied to the rear foot (rear-legged). The act of launching the swing will force the front foot down resulting in more weight being applied to the front foot and consequently less applied to the rear foot. And, yes, I do consider this to be an absolute among the best hitters.
Some people look at weight shift as COG (center of gravity or center of mass -- @pattar can correct me here, I'm sure.) If you have ever been a member at BBD, one of the members there (bluedog) talks about weight shift occurring prior to launch. What he is referring to is this movement of the hips towards the pitcher (COG or COM). I believe his phrase is "shift to the middle" -- @TDS can correct me on this as he is a member there as well. I don't think anyone disputes this claim from bluedog, its just that weight shift is viewed differently based on their point of view. And, yes, I believe the "shift to the middle" as defined above is also an absolute among the best hitters. Just a different application of weight shift.
FYI... Personally I find the whole turf war garbage to be tedious. I do my best to understand all parties and provide my understanding. But if i am incorrect on something I am perfectly fine with someone else correcting me. I consider the agendas that some want to pursue a waste of time.
