Why are NBA offenses soaring this season? Kings coach Mike Brown has some ideas.

Al Horford of the Celtics is a perfect example of a player who was strictly a post player when he entered the league 15 years ago but is now a forward/center who can shoot 3-pointers, score in the paint, and bring the ball up the floor and make plays.

“I still can’t really grasp my mind around it,” Brown said. “You can just see it in the development of young players. Before, everybody was like, ‘OK, you’re in 10th grade and you’re [6 feet 9 inches], you’re going to go down on that block and work on your righthand jump hook and lefthand jump hook.

“Because of what guys have been able to do and guys who have been able to change the game, like Steph and LeBron and [Kevin Durant], these guys do things out there on the floor for their size that you can’t even imagine. It gets translated now to guys watching on TV, and you’ve got guys that are 6-9 and 6-10 and they’re playing like guards were 30 or 40 years ago.”

With most players able to shoot 3-pointers and with the deemphasis of post play, the floor is more difficult to cover because players can shoot from 25-plus feet. And if you cheat and defend all shooters at the 3-point line, they will backcut to the basket for layups.

The Warriors discovered that three shooters, one handyman, and a quality defensive center can be wildly successful, and the rest of the league has been copying that formula for the past decade.

“Everybody can shoot. Everybody can pass. Everybody can dribble, and when you space the floor with players like that it just makes it so tough to try to stop a talented player because he’s kicking it to a guy that might be 6-8 but can knock down a three,” Brown said. “So when you’re flying at him, at 6-8, you’re not going to block their shot. Everyone wants to play faster because of the Warriors and the body movement and the ball movement, it’s unbelievable. I don’t understand how it’s like this now. I don’t know if it can stay like this, but I’m sure it’s fun to watch, especially from a fan’s standpoint.”

Some teams are unsuccessful because they can’t amass enough shooting talent. The Celtics are winning this season with offense because they added enough capable shooters to ensure someone will be open with proper ball movement.

“You have to have the shooters and the playmakers that can handle that type of freedom,” Brown said. “There comes a responsibility with freedom that you’re getting when you’re playing this way. You’re looking for good, quick shots. Are you willing to as a team embrace whatever role that your team needs you to do? If you have 17 guys that embrace their role, you’re going to have a chance just because individuals are so talented in today’s game compared to…
