The New York Knicks' dream of a perfect postseason run hit a wall Monday night as the San Antonio Spurs stole Game 3 at Madison Square Garden, cutting the Knicks' series lead to 2-1. But the loss wasn't the only thing getting people talking. All eyes were on the Knicks' bench—specifically on assistant coach Rick Brunson, father of star guard Jalen Brunson.

Late in the second half, Jalen took a hard foul that sent him crashing to the court, writhing in pain. While fans held their breath, Rick Brunson didn't hold back. He immediately jumped up, demanding the referees review the play for a flagrant foul. Video of his outburst has racked up nearly two million views on social media, and the reaction is not pretty.

ESPN's Computer Model Picks Spurs to Bounce Back in Game 5 After Knicks' Epic Comeback
ESPN's computer model favors the Spurs to win Game 5 at home after the Knicks' 29-point comeback in Game 4. Can San Antonio bounce back?

“I’m sorry but his father is way too emotional to be an assistant coach on his team,” one fan wrote. Another added, “He does this every time his son gets hurt. I get it but you’re a coach.” The criticism didn't stop there: “He is the coach that every opposing team parent hates at a 10u basketball game,” read another comment.

This isn't the first time Rick Brunson's sideline antics have sparked controversy this series. In Game 1, he left the bench to confront Spurs guard De'Aaron Fox after a heated exchange, shouting, “YOU NOT TOUGH, BRO. YOU NOT TOUGH.” The incident, captured on video, added fuel to the fire.

The debate is heating up: Should a father be allowed to coach his son in the NBA? Critics argue that Rick's emotional investment clouds his judgment and undermines his role as a professional coach. Supporters say it's just a dad looking out for his kid in a high-stakes environment.

He's been focused on the court, even refusing to touch the Larry O'Brien trophy before the series is over—a superstition that's become a talking point. Read more: superstitious or super focused?
