Hey there...beautiful swing from your daughter here.... I have been a hitting coach on the boys side for almost 10 years now.... and I was taught by a MLB coach in New York that the front leg should be firmed up at contact and the consequence for a bent front leg would result in a tremendous amount of Power... those were his exact words..... Is there a coach that works in softball that can give a good rebutal to why most girls are taught the bent leg theory??? I love being a student in the art of hitting and I know there are numerous types of swings but it is interesting to me on how far apart the MLB and the softball world are on this subject and Linear vs Rotation and then 50 50 between those two.... I see 3 different types of swings primarily being taught today.... and its fun to iron out all the pro's and the con's....
