Kenny “The Jet” Smith says it’s well beyond time for Charles Barkley and Michael Jordan to be greatest buddies once more … telling TMZ Sports his “Inside The NBA” cohost must do the appropriate factor and apologize for pissing MJ off a decade in the past.

“Apologize, Chuck. You were in the wrong,” Kenny mentioned … jokingly including, “He’s always in the wrong!! I don’t want to speak to Chuck today, either.”
