Golden State Warriors keep evolving, staying fresh in rivalry with Cleveland Cavaliers

* Tonight on TNT: Warriors vs. Cavaliers (8 ET)

CLEVELAND — You might expect, given the familiarity from what’s gone on for four years now, that the Golden State Warriors and Cleveland Cavaliers have worked up some serious mutual contempt.

They both covet what the other wants — in fact, the Warriors or the Cavs could make a persuasive case that, if not for the other guys, one already would have notched a three-peat and be chasing Bill Russell’s Celtics in pursuit of a fourth consecutive championship.

They both have poured buckets of blood, sweat, tears, money, Gatorade and offseason counter moves into their nouveau NBA rivalry. And they both, well, as Golden State coach Steve Kerr phrased it to the San Jose Mercury News Sunday, “We just want to kick each other’s ass.”

And yet the Warriors and the Cavaliers — who play again Monday at Quicken Loans Arena in the NBA’s prime-time MLK showdown — have more in common with each other than they do with any of the league’s other 28 teams.

Playing 100 games or so every year. Locking in mentally and surviving physically longer than anyone else. Showing up each night targeted as a measuring stick, even a season maker, by the opponents.

While trying like heck to keep things fresh. Renew. Find and tap into a new source of energy, because old ones wane over time.

“It’s the biggest challenge of this whole season,” Kerr told NBA.com late last week, with the Warriors starting a back-to-back in Milwaukee and Toronto on their way back to The Land.

Even if it were possible — and it realistically is not, given free agency, injuries, trades, the salary cap, luxury taxes, hirings and firings each NBA offseason — playing a pat hand from one championship-level season to the next isn’t desirable.

Voices, locker rooms, relationships get stale. Rivals adjust and escalate in the arms race. Some players ebb in the pecking order, others flow. It’s important to inject new faces, add skills and even find fresh themes to fend off monotony, even boredom, through the 82-game slogs.

The Warriors, in winning 20 of 23 games over the past seven weeks, largely have managed to do that.

The Cavaliers, at 26-15 after 2-7 stretch that started at Golden State on Christmas? Not so much.

Golden State shifts gears after each season

It’s easy to think of Golden State’s success since Kerr’s hiring before the 2014-15 season as one uninterrupted run of excellence. Three-pointers, “death lineups,” and the rest. But the differences from one year to the next have been fairly pronounced.

“In Year 1, we were trying to prove ourselves to the world,” Kerr said. “Then we win the championship — it was all so fresh. There were no letdowns at all that year. It was the most exciting, it was the most energized, it was the most refreshing. It was brand new to all of us. It felt like we were riding this wave all year — we were all giddy, like, ‘Oh my God, we’re really good!’ We didn’t know we could be like that. And for me, it was my first year coaching.”

Stephen Curry won his first MVP award. He and Klay Thompson generated considerable conversation about the best shooting backcourts in league history. Draymond Green forever changed the old NBA notion of “’tweeners.” The Warriors finished 67-15, ranked second in the league in offense (111.6) and first in defense (101.4) and beat Cleveland in the Finals in six games.

“It was maybe like the first stages when you fall in love,” Kerr said. “You’re just on Cloud 9 and she can’t do anything wrong. There’s infatuation and then you truly fall in love, and it’s amazing.

“The second year, we sort of rode that wave of euphoria of being the best team in the league and having won the title. The next thing you know, we’re 24-0 and we’ve got a chance to set an all-time record. That 73-win mark carried us all year. We were going to prove that, not only were we the champs but we were one of the best teams ever.”

The Warriors were — by regular season standards. Curry won his second MVP award. Kerr missed the first 43 games due to health issues but assistant coach Luke Walton steered them to a 39-4 mark. They bought into the chase for 73 victories fairly late, but instead of a 16-5 playoff run like the previous spring’s, the Warriors went 15-9 — coming up one victory short when the Cavaliers became the first team to claw back from a 3-1 deficit.

That led directly to Golden State’s next new wrinkle, a reconfiguration that came close to buckling the league’s knees.

“We got KD,” Kerr said. “Now we’re changing our team, right? Last year was about incorporating KD, welcoming this incredible player into our organization and our roster. Figuring how to do it, how we were going to adjust. I felt like there were times last year that were tiring, where our guys were done a little bit. But it was ‘new’ again.”

Even the challenges were fresh, like counting Curry’s or Klay Thompson’s touches relative to Durant’s or closing ranks around Golden State’s thin man as his reputation took blows for the first time in his NBA career.

Not interested in shooting for 74 victories, the Warriors simply took care of business and stayed coiled for the postseason. Then it was a 16-1 dash to title No. 2, Durant snagging the Finals MVP trophy after the five-game dispatching of the Cavs.

All of which just set the Warriors’ bar higher, requiring them to search for something new, somebody borrowed, presumably nothing blue.

“This year it’s just survive and advance,” Kerr said. “It’s ‘let’s get to April, May, June in one piece.’ There’s a reason we’ve lost six home games already. We don’t have the driving force that we had the last few years. We’re dealing with what any team in NBA history that’s tried to do this has dealt with. The Lakers (1982-85), the Celtics (1984-87, 1957-66)… It’s just really hard and you need that driving force.”

Said Warriors vet Andre Iguodala: “Your body is mindful of it, because it hurts.”

A couple of young guys — Patrick McCaw, Kevon Looney — have taken on bigger roles. Nick Young brings some sort of buzz into any locker room that will have him.

Still, as veteran guard Shaun Livingston said: “We’re not chasing any records. We’re not adding another All Star. We’re just trying to make it through the marathon.”

Cavs’ challenges mount during 2017-18

The Cavaliers are just trying to make it through the marathon, too. But if they could, they might do it like Rosie Ruiz, the 1980 women’s “winner” of the Boston Marathon who perpetrated a hoax by hopping the subway and running only the final mile of Beantown’s famous race.

The 2017-18 has been anything but fun for Cleveland so far.

It began with the departure of All-Star point guard Kyrie Irving, a not-so-funhouse mirror image of Durant’s arrival a year earlier in the Bay Area. Irving, for reasons still not quite explained, made it known in the offseason that he wanted out. He wanted to be the man on his own team. Or he didn’t want to be left in the lurch if (when?) LeBron James took his talents elsewhere again. Or both. Or neither.

Regardless, once the Cavaliers made his request come true by dealing him to Boston for All-Star point guard Isaiah Thomas and Brooklyn’s coveted first-round pick this June, their task got tougher and their season longer. Losing one of the league’s best ball handlers and shot makers doesn’t qualify as “renewal” any more than what went on in Oklahoma City when Durant packed up.

There’s been more. Shooting guard J.R. Smith seemingly got old overnight. Jae Crowder, who came from the Celtics in the Irving deal, hasn’t meshed with the Cavs’ style. Kevin Love has been moved to center but hasn’t done anything to satisfy the Cavs’ need for rim protection. Thomas only returned to action from a hip injury as the calendar turned to 2018 and has played only four games in these two weeks.

Even with so many new faces — seven of the top 12 in coach Tyronn Lue’s rotation weren’t here 12 months ago — it’s a group heavy on veterans, players a little too established or mature to naturally instill raw energy.

James said recently that none of this is new, it’s another case of the Cavs biding their time for the “second” season that means everything. But Lue also introduced the topic of “agendas,” suggesting that some of his guys were looking out for their own responsibilities and performances — particularly on defense — rather than the group’s.

At best, this is another dose of the midseason blahs, the Cavs in their doldrums in need of an All-Star break. At worst, though, they might be honing some bad habits that won’t be so easy to break in May or June. Especially if East rivals such as Toronto, Boston or Washington are emboldened after witnessing or administering some of the Cavs’ more embarrassing beat downs this season.

Will any of this matter come spring? It will if the switch each team is minding stubbornly decides not to flip.

“That’s the key. You’ve got to find that balance,” Kerr said. “Are you flipping the switch or are you navigating? The idea is, don’t let bad habits slip in. Right now, this moment, we’re into some bad habits. Our defensive efforts the last five, six games [before the weekend] were awful. We got away with it because Steph was going nuts.”

The Cavaliers repeatedly have not gotten away with bad defensive habits, even on nights when James has been dominant.

“It’s tough,” Livingston said. “They’re a team that’s built for the playoffs. But our core guys still are in there prime. Their core guys are still good. But we’re talking about ‘prime.’”

Most still would pick both Golden State and Cleveland to advance all the way to a “Finals Four” (after last year’s “Rubber Match” series). But one of these years, most will be wrong — about one or both. That alone might be motivation enough.
