Michael Jordan -- I'd DESTROY LeBron James in 1-on-1 ... But Not Kobe Bryant

Michael Jordan says there's only one guy who would beat him in a game of 1-on-1 ... and it ain't LeBron James -- it's Kobe Bryant.

MJ made the statement in a video promoting the NBA 2K14 -- while talking about a bunch of NBA legends he would've liked to ball against in their prime, including Jerry West, D-Wade, Carmelo, Kobe, LeBron and more.

"I don't think I would lose," Jordan says ... adding, "other than to Kobe Bryant because he steals all of my moves."

MJ was later asked who was the better player -- Kobe or LBJ -- and explained, "In terms of dominance in the game of basketball at this stage, it's LeBron."
