TMZ Sports saw Rodman at LAX on Sunday ... and asked him about the 76ers star's comments about his former Bulls teammate.

Embiid sent the NBA world into a frenzy during a recent episode of Ringer's NBA Desktop, when he said ... "[Jordan] is not the G.O.A.T."

"To me, you got Wilt Chamberlain. He’s got all the records, and no one is ever gonna beat them. I don’t see anyone ever getting 100 points in a game. That’s it, he’s the G.O.A.T.”

Rodman's take?

"Joel Embiid, you're doing a great job for your little island or country where you're from. Shut the f**k up, go do your goddamn job and do Philly proud. That's the 1 thing they need, a championship."

Just to be crystal clear DR didn't agree with Joel's take ... we followed up -- so, you're saying Embiid's wrong about Michael not being the greatest of all time???

"You're goddamn right he's wrong."

Rodman might be a little biased ... he played 3 years with Michael in Chicago -- winning an NBA championship each season.

Michael ('84-'03) and Wilt ('59-'73) played in different eras ... and both had ridiculous stats and an insane amount of accolades.

Jordan is a 6x NBA champion, 6x Finals MVP, 5x NBA MVP, 14x All-Star, 10x NBA scoring champ, 10x All-NBA 1st Team, 9x NBA All-Defensive 1st Team who averaged 30 points, 6 rebounds and 5 assists a game over his 15 season career.

Wilt was a 2x NBA champion, 1x Finals MVP, 4x NBA MVP, 13x All-Star, 7x NBA scoring champ, 7x All-NBA 1st Team, 11x NBA rebounding champ who once scored 100 points in a game and averaged 30 points, 23 rebounds, 4 assists a game over his 14 season career.

MJ is in the Basketball Hall of Fame and the FIBA HOF ... and Wilt's in the Basketball HOF and College B-Ball HOF.

We also asked Rodman if Embiid -- who's a pretty good hooper himself (he's arguably the league's most skilled big man) -- will ever himself be considered one of the all-time greats.
