Lonzo Ball just published an open and emotional Father's Day letter to his dad -- thanking him for everything in his life, advising him to ignore the critics and telling him that he loves him.

The entire letter -- addressed to LaVar Ball -- appeared on "The Players' Tribune" and is titled, "To the Loudest Guy in the Gym."

"One of the things I admire most about you is that you don’t really care what other people think. People can have whatever opinions they want about who you are as a person, but they’ll never have all the facts. They’ll never know you like I do."

Lonzo reflects on impactful family moments including workouts, road trips, basketball games and family breakfasts.
