Look out Ryan Lochte, there's a new guy in the pool gunning for gold -- 7'6" Boston Celtics center Tacko Fall!!
Of course, the fan favorite giant has been using his free time in the NBA bubble to try out some new sports ... including hitting the links to golf with Orlando Magic center Mo Bamba.
The big guy is now taking on another challenge -- swimming -- and jumped in the pool with his teammates Jaylen Brown and Enes Kanter for his very own lesson.
The results are hilariously awesome .
