That's what I thought. See earlier posts^^^ but in real time you can see the ball spinning the whole way. And contemplating the action, It doesn't appear the ball would pick up that rotation from glancing off either ball.He may have spun it ....(but he did say just a bit and ever so slightly)....I watched the frame by frame just before the "WHOOO!".......using the dots.....the ball looked (to me) to be in full roll just before contact.
