The coach whose club has been the poster child for the NBA’s offensive explosion believes the league must give defenders an opportunity to respond.

Before the Golden State Warriors faced the Toronto Raptors on Friday night, Steve Kerr suggested the NBA has gone too far in giving offensive players an advantage.

“I think there should just be a basic rule: no bulls— allowed. Really. “That’s the truth,” Kerr stated. “And I could show you a clip of a player dribbling off a high ball screen, the defender attempts to fight over (the screen), the man (with the ball) hops backwards, and the ref rules a foul. So, what are we doing? Can you picture calling that during a pickup game? It would start a battle. We just need to get back to determining what basketball is.”

Last year, the Sacramento Kings broke the NBA scoring efficiency record by averaging 118.6 points per 100 possessions. This season, five teams—the Boston Celtics, Indiana Pacers, Oklahoma City Thunder, Milwaukee Bucks, and Los Angeles Clippers—were above that level going into Friday night’s games.

The Warriors won their fourth championship during a seven-season run that began in 2014-15. They had an explosive offense, scoring 110.4 points per 100 possessions, second only to the Clippers. This year, all offensive save the lowest four had a higher scoring efficiency.

Beginning with its 2015 championship, Golden State placed second, first, first, third, and first in offensive rating for five straight seasons. Built around the explosive shooting of Stephen Curry, Klay Thompson, and, later, Kevin Durant, the league struggled to adjust to the amount of space created by the Warriors.

At the same time, players across the NBA, including James Harden and Trae Young, began to make contact with seemingly little regard for scoring a basket — only getting to the free-throw line.

“Let’s make players create an advantage in order to call a foul,” he remarked. “But we have these identical phrases: prohibited guarding position. Sometimes a player may simply slam right through a defender, and the ref will call a foul on the defender. The referee will declare, ‘It’s an illegal guarding position.’ The referees must make that call.

“That is how they are assessed and trained. As I already stated, the authorities are excellent. It’s just that we need to realize what’s going on. I believe it’s been about a decade that offensive players are so smart that they see what’s going on and absolutely manipulate the rules to let them go.”

In recent years, the league has made certain changes, such as limiting the types of motions that result in shooting fouls rather than just ordinary fouls. The league also eliminated the “rip through” foul, which occurs when a player with the ball moves his arms awkwardly to make contact with a defender, though variations of it continue to be called.

Kerr mentioned that in his final season as a player, 2002-03, the San Antonio Spurs defeated the New Jersey Nets in six games. Only twice during that series did a team score more than 90 points in a game.

“That was dreadful. “The league has had great intentions, and we’re in a great position,” Kerr said. “But you always have to be looking ahead and balancing things. We must give the defense more of a chance. It all starts with not aiding the offensive players and bailing them out for bullshit—things that they’re doing, really.”
