I see his problems.
It’s his stance, elbow, bridge, shoulder, head, vision center, tip, shaft, chalk, pocket size, dominant eye, shoes, glove, cue angle, cue weight. focus , etc.
Almost forgot Aiming.
Too many to mention.
The guy is a mess.
Filler is the most gifted player in the game, his timing is second to none.
If you have a chance to see him play live go, and listen to the ball clicks, it’s poetry in motion.
Streams don’t do him justice.
