Horace Grant Blasts Michael Jordan Over 'Last Dance,' You're a Snitch!

Horace Grant is going scorched-earth on Michael Jordan -- claiming 'Last Dance' was filled with "lies" to make MJ look good ... when in reality, Jordan is nothing but a "snitch."

Yeah, man, Horace is PISSED!!

Of course, Horace participated in the ESPN docuseries -- most memorably to deny he leaked sensitive information about MJ to Bulls reporter Sam Smith back in the day.

Bottom line -- it became abundantly clear the two men don't like each other ... and haven't gotten along in years despite winning 3 NBA championships together.

Fast-forward to Tuesday when Grant appeared on the "Kap and Co" radio show on ESPN 1000 in Chicago and was asked straight-up if he was the Sam Smith leak.

"It is a downright, outright, completely lie," Grant said ... "Lie, lie, lie."

"If MJ had a grudge with me, let's settle this like men ... Let's talk about it. Or we can settle it another way. But yet and still, he goes out and puts this lie out that I was the source behind [the Sam Smith book Jordan Rules]."

Grant strongly believes MJ still holds a grudge against him -- "And, I think he proved that during this so-called documentary."

"When if you say something about [Jordan], he's going to cut you off, he's going to try to destroy your character."

That's when Grant brought up Charles Barkley -- and how MJ cut off their decades-long friendship after Sir Chuck criticized his management of the Charlotte Bobcats on TV.

"Charles Barkley, they've been friends for over 20, 30 years ... and he said something about Michael's management with the Charlotte Bobcats or the Charlotte Hornets, and then they haven't spoken since then."

"And, my point is, he said that I was the snitch, but yet and still after 35 years he brings up his rookie year going into one of his teammates' rooms and seeing coke, and weed and women. My point is: Why the hell did he want to bring that up? What's that got to do with anything? I mean, if you want to call somebody a snitch, that's a damn snitch right there."

Grant then criticized the docuseries as a whole -- acknowledging it was entertaining but says 90% of it was "B.S."

"It wasn't real -- because a lot of things [Jordan] said to some of his teammates, that his teammates went back at him. But, all of that was kind of edited out of the documentary, if you want to call it a documentary."
