by I/R positions I mean positions that are loaded and ready to rotate towards the body as opposed to positions where rotation has already occurred.
Can you describe the motion you are comparing it to? There really are not that many options, either the hand is outside, on top of, inside or under a ball at release or some combination of adjacent positions. Outside and on top are NON I/R positions, under and inside are I/R positions. I can't even imagine how you would get any semblance of backspin if you were on top of, or outside of, the ball.
I'm frequently asked: "How do you teach 4 Seam Riseball Spin?"........Here's a snippet from a recent session with another PC........
Just read 2020, that seems like the way I will teach my daughter. Just seems to tough to throw a rise ball and end up Palm down.
