(UPDATE) I'm adding the red/blue scrimmage, which includes dunk contest....44" vertical video is here as well but is a seperate video. Ayton has had ?? marks on his motivation offensively. I've been scouting him since his soph year and he does have issues being passive offensively ( not defensively) in big games....mostly not using his natural talents and shooting abilities to score. In this scrimmage he had 21 points and 9 rebs but showed his shooting touch. BTW he looks absolutely ripped. New Video: https://www.youtube.com/watch?v=d7tqOZ0TiQE
Never lifted weights before college and as a hs soph recorded 28.5" no step and 34.5" max vertical tested at UA camp. Biggest thing to remember is that he is freakishly long: 7'5.5" wingspan and 9'4.5'' standing reach....both of which could increase if he goes to the combine.
This is a video of him taking off from one foot and getting a 44'' max vertical. I know he's not taking a couple steps and going off 2 feet but it atleast shows he is a very strong 1 foot jumper and that can translate to better first step and speed. IMO I like 1 foot jumpers more.
