Okay i have a question regarding the back foot of hitters. We’ve all been told to rotate the back foot to get the hips through but i’ve noticed something different about all these big time major league hitters dating back to the babe and mantle. They all seem to rotate their back leg/knee in moving their back foot forward, not so much twisting, to the point where sometimes their foot even comes off the ground. Take a look at these video clips and let me know what you think of this.
