Future NBA lottery pick Obi Toppin and his brother are taking each other to new heights during the COVID-19 pandemic ... by literally JUMPING over each other in an insane dunk session!!!
Of course, Obi was one of the best players in college basketball with the Dayton Flyers last season ... and younger bro, Jacob, will star at Kentucky after playing one season at Rhode Island.
The brothers proved they BOTH got incredible hops in a vid posted to IG on Friday ... doing one-handed windmill dunks while soaring over each other.
To put things into perspective -- Obi is 6'9" .
