Scott Ostler: Cavs must find a way to adjust.

Cleveland’s strategy is not exactly new

How do the Cavaliers even have a chance? It’s the Cavs’ five against the Warriors’ six, if you count Rihanna.

She sat courtside for Game 1 on Thursday at Oracle Arena, openly rooting for LeBron James and his Cavs, and apparently talking trash to Kevin Durant. Took Durant right out of his game. Killed his spirit. He was held to 38 points, eight assists and six monstrous first-half dunks.

Bob Myers, the Warriors’ general manager, said Saturday he was pretty sure the Warriors did not comp those courtside seats for Rihanna and Jay Z. For Game 2, the Warriors

comp the seats — and send a limo to pick up Rihanna. Give her a bullhorn.

The hard truth is that LeBron James and his Cavaliers are in deep trouble. All the King’s men and all the King’s favorite hip-hop artists aren’t going to help ’em out of this jam.

Yes, it’s only one game, and I do recall last year, when the Warriors went up 2-0 and 3-1 against the Cavs and wound up blowing the Finals. This is way different.

Let’s zero in on the Cavaliers’ task at hand: Their most glaring problem in Game 1 was the flurry of Warriors’ uncontested dunks in the first half. The Cavs must take away those embarrassing swoops to the hoop. They might try asking the league to park a Kia sedan in the paint at each end of the court. Blake Griffin did that a few years ago in the dunk contest, and it made his dunks more difficult and more entertaining.

Expect the Cavs to slow down the dunk carnage because, as Kevin Love said Saturday, “That’s what stuck out on film the last two days.”

That, and everything else the Warriors did splendidly.

There are many things the Cavs can do to try to improve — stop the easy dunks, run more, be more physical, take better care of the ball, take their trash with them when they get off the team bus. But none of these strategies is likely to have much effect.

The Cavs adjusted after

being down 3-1 last year, but it’s possible that no team in NBA history has improved from one Finals to the next as much as the Warriors have. Here’s what they have this time that they didn’t have last time: Durant, a healthy Stephen Curry and a Draymond Green determined to play every game of the Finals.

The Cavs are also improved over last year, but not like the Warriors.

The Cavs aren’t about to admit that right now. They’re busy plotting their chess moves for Game 2. Their main objective is to be more physical.

“Just making them feel us, the level of physicality,” Love said when asked what the Cavs have to upgrade.

J.R. Smith said the Cavs must get physical with Curry and Durant by working them harder. Make them feel it when they cut through the lane without the ball.

That’s great strategy, and here’s why it’s not likely to

make a difference: That’s what every team the Warriors played this season tried to do.

In fact, tracing the Warriors’ path through the playoffs for the past three seasons — a fairly successful trek — every time they got the lead in a series, the other team said, “We’ve got to get more physical. We’re being too nice. We have to play with an edge, play tougher, hit ’em harder.” It never worked. The Warriors are like the pretzels sold by street vendors in New York City. They look all soft and gooey, but they’re hard as diamonds.

Opponents have been clutching/grabbing/smacking/bumping Curry for the past three seasons (or more). Steph doesn’t like it, his team protests by sending video to the league office, asking for more foul calls and free throws, but the beat goes on. Result: Curry gets his 28 points and the Warriors get another win.

Roughing up Durant is more of a challenge. He moves so well and is so tall that defenders can’t get a good whack at him. He’s like a swinging pinata.

Klay Thompson is one of the sturdiest two-guards in the league, and Green is a hard guy to push around.

The Warriors might be a finesse team, but they’re like the old Showtime Lakers and the old Walsh 49ers and those NYC pretzels. As Ronnie Lott might say, “I got your finesse right here.”

I asked Warriors’ center Zaza Pachulia if he expected the Cavaliers to come out more physical in Game 2.

“Absolutely,” Pachulia said. “They’re already talking about it, it’s obvious, we expect it, and we gonna do the same thing.”

The Cavs better hope Rihanna steps up her game.
