One week ago, Draymond Green made his feelings felt on Instagram following controversial comments by NFL team owner Bob McNair.

Now, according to a report from ESPN’s Tim MacMahon, Dallas Mavericks owner Mark Cuban wants the Warriors forward to apologize.

Cuban did not dispute the wrongfulness of McNair’s initial statement, which included referencing NFL players as “inmates.” The Mavericks owner, however, took issue with Green’s response, which questioned the title of team “owner.”

Wow! This sure does sound very Donald Sterling-esque. But I'm sure the fans pay to see him play and he's putting himself at risk of CTE by going out there every Sunday and giving 110%! Inmates? For starters, let's stop using the word owner and maybe use the word Chairman. To be owned by someone just sets a bad precedent to start. It sets the wrong tone. It gives one the wrong mindset. Webster states that an inmate is a person confined to an institution such as a prison or hospital. Not sure these tax paying men should be referred to as inmates- but what do I know?

“For him to try to turn it into something it’s not is wrong,” Cuban told ESPN. “He owes the NBA an apology. I think he does, because to try to create some connotation that owning equity in a company that you busted your ass for is the equivalent of ownership in terms of people, that’s just wrong. That’s just wrong in every which way.”

This isn’t the first time Cuban and Green have engaged in a war of words. As the 2016 NBA playoffs were underway, the Mavericks owner said he did not consider Green to be a superstar, saying, “Draymond, he makes all the players around him better, but I don’t think he goes anywhere in the league and wins 50 games.”

Green declined to address Cuban’s comments when approached on Saturday. He did bristle, however, when asked if he’d been advised not to comment.

“Nobody can prep me,” he said, as reported by ESPN. “I’m going to always say what I want. Ain’t no prepping me. At all. Ever. Don’t ever believe that. Can’t prep me for nothing. Don’t ever think that. I do live in America. However, you can’t prep me for nothing. Don’t ever think I’ve been prepped for an interview. Don’t work like that.”
