I read the column and watched the video. I'm not going to defend Cousins' use of profanity or his bullying, but I do think it's silly that some people are clamoring about censorship without, apparently, realizing that Cousins is also exercising one of his rights—freedom of speech.
He's well within his rights to be upset at someone's coverage of him, even if you think he shouldn't be upset; and he's well within his rights to say (or not say) what he wants to say (or not say). The NBA's rules don't specify the details of a player's media "availability," they say only that he has to be available. If he's there in the locker room (which he has been), that fulfills his requirements. If certain people want him to be forced to give more (which is itself an ethics violation, in my opinion), it would have to be done through the collective bargaining process.
And yes, I still want him on the Celtics.
No one is saying he shouldn't speak his mind, but there's a way mature adults should conduct themselves. The reporter is half his size and appears to be more than twice his age, he could've easily pulled him aside and had a private conversation with him to let him know how he felt. Approaching him like that was completely unnecessary and it was clear he was trying to intimidate him.
Players do this. They are confrontational. They compete for a living. Melo once waited in front of the Celtics bus to confront KG. Intimidation is part of the package. Look at Perk's face.
You can't just put your intimidation hat on when it's time to play basketball and then leave it in the locker-room after the game. It's something these guys have been working on their whole lives, and there's no way Cousins or Garnett would be that intense on the court if they weren't as intense as they are off the court.
Throw in family, and tempers can heat up real quickly. Cousins didn't flip out because the guy gave him a bad report. What the guy was doing had no impact on basketball at all, it was directly personal toward Cousins. He's not running for president, he's trying to make a living. His brother could have his career/life ruined or something over the exposure.
I'm not excusing Cousins, I'm just trying to explain that it's not "easy" to "pull him aside and have a private conversation with him to let him know how he felt" unless Cousins is in cold blood (which clearly I don't think he was). Pretty sure Cousins already knows that's not how mature adults are supposed to act, he just couldn't control himself.
