In my opinion there isn't a better way, it's unique to each pitcher. Some kick, some balance oddly, some have wild and/or deceptive movements. I believe a pitcher is born. You can tweak them a bit but they throw how their body tells them they can. They could have tight hips, weak knees, or something else they compensate for, but when you get into true pitching in high school and beyond I truly think those are the kids who have always pitched like that. A true pitchers velocity and location ability is something I truly think they are born with. Sometimes you can teach one or the other, but not usually both.
