NBA star Zach LaVine has high ambitions in Chicago ... but can the high-flyin' dunk master jump over the Jumpman and pass Michael Jordan as the best Bulls dunker of all time??

That's exactly what we asked LaVine -- who was just recently traded from Minnesota to the Windy City -- and while the 2-time dunk contest champ has some serious hops, he doesn't think he'd ever match His Airness' classic moves.

It's a pretty humble response from LaVine, who's only 22 years old and has already put on a dunking clinic in just 3 years in the league ... but we get it. It's M.J. we're talking about.

We also asked about getting traded away from the T-Wolves ... and it's nothing but love for his old squad.
