Spin does not play tricks, speed does. Have you ever played the game before or caught a baseball pitcher Serious question?Agree spin can cause tricks.
Especially on change ups.
Are you going to explain your previous comment of throwing pitches with the same spin???
Not to be snarky here...
Rather to discuss your point to throw pitches with different movement and use the same spin?
And what spin would you suggest to use?
Are you saying mechanics would change?
Right toooo many questions
Is a sinker, cutter, and a 2 seam basketball are all the same pitch. Finger pressure will dictate what happens in flight. In baseball you can also change your arm slot
The holy grail is a pitch with multiple speeds from the same arm motion, same spin, and different speeds
