But there are mechanical motions in baseball that can give us the edge over others too, leg lift and tilt / falling action and posture / arm extension / hip shoulder separation / front drive extension / shoulder tilt / arm slots. It's not as easy as just standing up there and throwing, if you want to be any good.
Baseball has rules about the rubber and feet just like softball, but they are enforced in baseball, hands together / separation / quick pitch / pick off stepping / set position / complete stop / when he can/must/can't step on/off the rubber.
I know we beat this dead horse all the time on DFP, but where does the blame need to go? Is it the PC's who teach bad mechanics, is it the coaches who can't see it or don't want to mess with it, is it the umps who don't call it?
I think it is beacuse the leap and drag can very easily become the jump and not drag. It is something that is fairly easy to watch for as parents and they yell bloody murder even when a girl is legal but looks illegal because of the hole that's been dug in front of the pitchers plate.
God forbid their little Suzie strikes out becuase the opposing 10 yo pitcher jumped 2 inches too high.
In baseball, most parents have no idea what is and what isn't a balk or what to even look for so they don't scream about it as much.
