Majority of players would benefit for having some foot flare, however, super elite athletes that have ability to load the hips and glutes would reduce that foot flare, because they have range of motion in the pelvis. Good example of this would be hank Kuehne.
Hi Dana, at one point the student asks how he should be applying vertical through his lead side with his pelvis feeling more back. Is there a difference in how vertical force is applied through the lead foot/leg for pelvis forward vs pelvis more centered and back?
Yes correct, you don’t “if you want to hit it farther’ get the mass over the center of pressure. It can be substantially different as a feel for many. Hence why there several different patterns I’d teach.
