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.
