At what point does enough become enough?

Draymond Green was caught on camera reaching for Jabari Smith Jr.'s ankle after the whistle in the Warriors-Rockets game. The video is clear - the play was over, and Green reached down for Smith's ankle.

This is the latest in a long history of questionable plays from Green, and honestly, I'm running out of patience here.

Look, I understand Draymond is an intense competitor. I get that he plays with an edge, that he's physical, that he does whatever it takes to win. But there's a line between playing hard and playing dirty, and grabbing a player's ankle after the play is over? That's dirty basketball.

It's dangerous, too. Ankles are vulnerable. Players plant and cut on those joints constantly. A twisted ankle can end a career, or at minimum, sideline a player for weeks. And Green knows that.

Jabari Smith Jr. is a young player for the Houston Rockets, trying to establish himself in the league. He shouldn't have to worry about opponents grabbing at his ankles when the play is dead.

This isn't Draymond's first rodeo with controversy. He's been suspended for flagrant fouls, he's gotten into altercations with teammates, he's had multiple incidents that raised questions about his on-court behavior. At some point, the NBA needs to send a clear message that this stuff won't be tolerated.

I've defended Draymond in the past when people criticized his physicality. Playing defense requires toughness, requires being willing to get in someone's space. But this isn't defense - this is after-the-whistle nonsense that serves no purpose except to potentially injure an opponent.

Fans on social media are calling for discipline, and they're right. The league office should take a hard look at this and determine whether supplemental action is warranted. Because if you don't punish these kinds of plays, you're essentially giving players a green light to keep doing them.

The Golden State Warriors are fighting for playoff positioning. They need Draymond on the court, focused and locked in. They don't need him making headlines for all the wrong reasons.

Here's what frustrates me: Draymond is a four-time NBA champion. He's one of the best defensive players of his generation. He doesn't need to resort to these tactics - he's good enough without them.

But when you keep crossing the line, when you keep putting other players at risk, at some point your reputation becomes "dirty player" instead of "tough competitor." And Draymond is dangerously close to that point.

The league needs to protect players from this kind of behavior. Whether it's a fine, a suspension, or just a warning, something needs to happen. Because grabbing an opponent's ankle after the play is dead isn't basketball - it's bush league.

That's what sports is all about, folks - except when it crosses the line into dangerous territory.
