Chances are, the NBA was not serious about suspending Stephen Curry for the Warriors’ final opening night in Oakland because he and DeMarcus Cousins bolted off the bench as others scuffled on the floor in Friday night’s exhibition finale against the Lakers.

Still, the league looked into it, and head coach Steve Kerr could not dismiss it until the league did.

“If this were 15 years ago, Steph would not have been allowed at Oracle on ring night because he stepped on the floor,” Kerr said after Sunday’s practice in downtown Oakland, two days ahead of Tuesday’s opener against Oklahoma City.

“Fortunately, we have a different interpretation of the rule now. We’re lucky he got away with it, and DeMarcus, too.”

Now Playing:

Thus, the Warriors will be whole when they raise the championship banner for the third time in four years, depending on one’s definition of “whole.”

Curry and Shaun Livingston did not participate in a scrimmage Sunday. Though they were officially getting “rehab days,” Kerr said Curry had a “minor little tweak that we didn’t want to mess around with,” and Livingston “the same thing, just a minor deal.”

Curry’s ailment (not his ankle) will not keep him from starting Tuesday night, Kerr said, declining to identify the precise injury.

“It seems like we have to report a hangnail,” he joked, “so just call it a hangnail.”

Kerr has other concerns.

He plans to limit Draymond Green’s time on the court initially because the forward is behind in conditioning thanks to a knee injury that curtailed his preseason and had him “gassed” during Friday night’s game in San Jose.

Limiting Green’s minutes could impact a defense that slacked enough during the two exhibitions against Los Angeles that Kerr ordered a “defensive segment” to Sunday’s practice ahead of the scrimmage.

“I was really pleased with camp after two weeks,” Kerr said. “Then the last week was kind of a mess. Our defense was atrocious the last couple of games: basic stuff, not boxing out on free throws, back cuts, transition defense.

“I attribute some of that to preseason and guys losing interest. I’ll tell you after Tuesday night if it’s just our bad habits right now. If it is bad habits, we’ve got to get out of that.”

The Warriors are like any team in any sport. It’s like a play. No matter how good the actors are, the director lies in bed after the final dress rehearsal with indigestion.

Oklahoma City head coach Billy Donovan might need the Pepto-Bismol even more. His team’s injury report has been stacked all preseason, and his point guard, Russell Westbrook, is questionable for Tuesday night as he continues his comeback from a knee operation.

The Warriors have watched video of the Thunder’s recent exhibitions without Westbrook and will game-plan either way.

It’s hard to imagine the Warriors playing atrocious defense or atrocious anything after another ring ceremony and banner raising, knowing this will be their final opener in Oakland. Next year, it’s on to Chase Center in San Francisco.

“You don’t take these for granted because they’re rare to come by, and we’re going to soak it all up,” shooting guard Klay Thompson said. “It’s going to be so much fun, seeing that banner being hung up, and just the competition that the Thunder will bring out in us.”

Thompson talk: Thompson’s father, former Lakers center/forward and current team broadcaster Mychal Thompson, joked that the two Warriors-Lakers exhibitions were the first of 13 meetings between the teams, intimating that Los Angeles will see Golden State four times in the regular season, then meet for seven games in the postseason.

Klay Thompson laughed and said, “He loves running his mouth. He can keep talking. He’s good at it.”
