Then why does spin axis matter? When you get to a certain speed (not exactly what that is) assuming you are somewhere between bullet and back spin at 35 or so feet at release, the ball is not going to drop so why does spin orientation matter?
Why learn how to cook when there's a drive though on every corner?
Why learn to drive when you could call an Uber?
Why learn math when we have calculators?
Point is, I could skip a shower if I wear cologne... but I'd still be dirty, just wouldn't smell as bad.
Learn the correct spin, and do it right or don't bother. You have to enjoy the ride. Learn something new and more efficient every day.
The girls on tv throwing bullet spin "riseballs" are somewhat effective because they're athletic freaks of nature. So, unless your dd falls into that category, learn the correct axis, and be successful at higher levels because she's actually throwing a real rise balls, and has worked her tail off to get there. There are 2 reasons Barnhill has one of the lowest (if not the lowest) ERA's in the country... 1. She has a real back spinning rise. & 2. She's an example of that athletic freak. Gotta be one or the other to play at the highest levels!
