That kind of scares me. If you use RVP. The question would be what difference is there watching a baseball swing and a softball swing? I have watched many in slow motion with 14 frames on each. Different Styles , but the swing is the same. what that is.
Well I was cheering you on till you talked about the baseball swing being different from the fastpitch swing.I have access to a pretty good college level hitting coach. She told me never to teach anything to a player if you can't answer WHY you are teaching it. Why do we stride? Why do we keep our weight back? Etc. Especially with young players. So I agree with Mark, learn the swing and why it is done that way. I use her drills exclusively because she has explained to me why. I had to "unlearn" my baseball swing first and build my own swing to be able to show my team a sound softball swing.
Just my humble opinion, but at the 10U level I would make sure to not give them anything more then get in an athletic stance, keep the barrel up, take a small step and swing - keeping your head still and your eyes locked on the ball. Too many drills at this age suck the athleticism out of them...You can never screw them up by letting them develop athletically and be a gentle guide. Too much instruction at this age is counter productive - again IMHO...I think the coach we use gets a lot of her drills and info from Cindy Bristow. Is it worth looking into Candrea's methods? The girls I work with are all 10U (7 to 10 YOA) I want to be able to give them the best information possible so that I don't screw them up. You know have me doubting our hitting coach, since she gave me the basis to teach the girls.
