Draymond Green already has a problem with Charles Barkley.
And now, he might have an issue with Kendrick Perkins, too.
Near the end of episode No. 6 of "The Last Dance" documentary on the Chicago Bulls that aired Sunday night, Perkins took to Twitter.

He posted this because the show featured the 1993 NBA Finals between Michael Jordan's Bulls and Barkley's Phoenix Suns.
Over the course of the series, Barkley -- who was named NBA MVP that season -- averaged 27.3 points, 13.0 rebounds, 5.5 assists and 1.2 steals. Unfortunately for him:
The Bulls won in six games.
"I have no problem losing to Michael," Barkley said in the show. "Losing to Michael -- there's no shame in that. Sports are like a gun fight. And we lost to the fastest gun."

Draymond, of course, has reminded people over the years about how the Hall of Famer never won an NBA title.
"Barkley should stop (talking about me) before I go take his job, though," Draymond told reporters in early March. "Because I can do that well, too. He needs that job so he should stop talking (about) me.
"I have a tendency to end people, so he should stop before I take his job. If he keeps talking, I'll take it soon. Sooner than he thinks. So he probably should be quiet.
"He also can't talk basketball with me. Not smart enough, not qualified, no rings -- can't sit at this table."

Draymond is very smart and knows that Barkley was an incredible basketball player. But he likes to bring up that Sir Charles doesn't have a championship ring because, well, that's just what you do when you're talking trash.
Also -- it's personal for Draymond.
"As someone who may do TV after I'm done playing ... I'm always the guy trying to look out for the young guy," he explained on Showtime's "All the Smoke" podcast last month. "Speak the truth on basketball. Speak the facts. But I think we all know -- and it's no secret -- that Charles Barkley don't study basketball. Charles Barkley get up there and talk out the side of his neck.
"I don't have an issue with somebody critiquing my game -- critique my game all you want ... but he like to throw shots and s--t. And it's like, bro, the jealousy gotta step. I'm a young black man that came up after you. You essentially paved the way. Appreciate the way that you paved and stop f--king hating."
Perkins has said some very nice things about Draymond recently, so you probably shouldn't expect any type of response from the 2017 Defensive Player of the Year.
But you never know.
