Could you post video of you just playing catch. Nothing fancy, not trying to rifle the ball, just a relaxing game of catch.
-don't try to pitch, just throw for a simple game of catch, at a distance of about 60 feet.
-first play a game of catch on a flat, level surface with no holes or other surface conditions to distract your throwing.
-second, go onto a pitching mound that's conditioned without holes or eroded surface marks, and continue a game of catch. Again, don't try and rifle the ball, simply throw enough to reach the other player, about 60 feet away.
I'd like to see how you move naturally without the force of full game speed.
