No matter what you think about LaVar Ball's antics when it comes to his sons, you gotta respect it ... so says Matt Barnes who tells TMZ Sports at the end of the day, he got 'em all to the NBA.
Remember, LaVar has aways been his boys' official hype man for years -- praising Lonzo, LiAngelo and LaMelo any chance he gets ... promising fans (and haters) they would all be in the big league.
LaVar ended up being right ... Gelo is on a G-league team, Zo is dominating with the Bulls and Melo has brought the Hornets back to life.
