Mac McClung is the back-to-back NBA Slam Dunk champion, but even he has his doubts about going at the King ... telling TMZ Sports he'd "probably" lose to LeBron James in a contest!!
The 25-year-old G League star wowed the crowd yet again during All-Star festivities this past weekend ... edging out Celtics star Jaylen Brown to take home the trophy in Indy.
We spoke with the high-flying athlete about what's next following his big victory ... and while he's planning to finish out this season strong before going back to the drawing board for new dunks, there's one thing you can probably take off his "To-Do" list -- a showdown with LeBron.
"[LeBron's] the man, I don't know if I'd want to go up against him," Mac told us during his celebrity shift at Raising Cane's in Orlando. "He'd probably beat me, for sure."
Worth noting -- LeBron famously never did the dunk contest ... something fans practically begged him to do for years, considering he's one of the greatest rim-rattlers in league history.
Despite the lack of experience in the event, Mac thinks the Lakers superstar would be his biggest competition yet ... even at 39 years old.

Mac admitted he's still on the fence about whether he'll go for a three-peat ... but if he does, he's just looking to go up against anyone who actually WANTS to participate.
There's more ... Mac also weighed in on his drive-thru shift at the chicken finger joint ... and he's a natural!!
