He's 6'5" or 6'6" and can do a between the legs (in the air) dunk strolling up to the rim from the 3 point line.
I remember when Isiah (a.k.a JR) Rider won the NBA dunk contest with his 'East Bay Funk Dunk'. This was circa 1992. Rider had to start baseline from out of bounds to do that dunk.
20 years later 18/19 year old college freshman like Brandon Hutton can do that dunk walking in from the 3 point line
