Dennis Rodman Says His Son's WAYYY Better Than He Was At BBall!!

HOFer Dennis Rodman is one of the greatest rebounders ever ... but he's not even the best hooper in his family ... 'cause Dennis says his son's a "way better" player than him.

TMZ Sports saw Rodman -- a 5x NBA champ -- in L.A. earlier this week ... and asked the "Worm" about his teen son, D.J. Rodman ... who's a beast on the court.

D.J. -- who plays at Corona del Mar H.S. in California -- is only a sophomore. Still, the way Rodman describes his son, the kid's gonna be rockin' an NBA uni one day soon.
