*The mouthpiece was deliberate, but I don't care about that. What I care about is his sprinting off the court like a 5 year-old when he didn't get his away, only to come back relatively calm (till cameras were in front of him again for an interview) once he did. That's next level immaturity. Imagine him in our locker room? We don't even have it together yet... not even close. I'm not sure Brad could discipline a baby doe, either.
I find this view odd. I don't care about the mouth guard thing either (and many players from Steph Curry to Amir Johnson have had worse mouth guard incidents than that). But the way he exited the court? If anything I thought that showed complete self control and discipline (at least for a brief moment).
This is the NBA after all, where we've seen players have to be held back from arguing with the refs after an ejection, or roll their eyes as they take their sweet time to leave, refuse to leave the court, make obscene gestures on their way out, throw their jersey into the crowd, kick the ball into the stands, etc. And you have a problem with him just running off the court instead? Personally, I feel like that's the best way to handle it. I have no idea what went through his head, but my guess is it was something like, "if I stick around I'm going blow up and get fined/suspended, let me leave the court NOW before I do something stupid." Again if I had to guess, I'd say he channeled his anger into running off the court instead of yelling at the refs.
Out of all ways I've seen players handle ejections in the NBA, I feel like just running off the court is better than 90% of them. Had he not just run off the court, and instead cussed the refs out or made a big scene out of it, do you think they would have reversed the call? I don't.
A lot of places we can call out Cousins for immaturity, I don't think running off the court is even close to one of them.
(I do think it would be hilarious if he threw his jersey into the crowd, only to have the call reversed though, ha).
