Charlie, appreciate your post.
I bet he can get into details but he had very short time and two tips to give to general population. Maybe he saw a trend of too much spinning the ball without enough 'through'. Whatever the reasoning there must be some value to it since it's from someone who has achieved the worldclass skill level. Just something to think about and maybe such message will stick to people who's overspinning without hitting through the ball. It's all a balance act. I don't believe in one or the other. both through and spin components are valid and essential i believe. It just happens to be the latest tip from a pro to general population.
