BOSTON — As Stephen Curry emerged from an area tunnel for his pregame warm-up routine, he was the middle of gravity, drawing followers to him as he usually does defenders on the court docket.

The Golden State devoted within the stands — who seemed to be within the dozens — dangled sneakers and posters into the tunnel for Curry to signal, or in any other case leaned over one another to get a greater take a look at him. Ian Rea, a 16-year-old who drove together with his dad and mom from Saint John, New Brunswick, held up an indication that mentioned, “Steph, for those who signal my jersey, I’ll minimize all my hair.”

The meticulous mixture of Curry’s jumpers, floaters and trick pictures with a touch of goofiness is the basketball equal of watching Louis Armstrong run scales on the trumpet.

Curry didn’t find yourself signing Rea’s poster. However a number of rows away, watching Curry run his personal scales, Matt Velasquez, 49, a flight attendant, was wistfully contemplating the idea of basketball mortality Friday night time, with Golden State then down a sport to the Celtics within the N.B.A. finals.

“You might be coming to an finish of an period,” mentioned Velasquez, who’s from Danville, Calif. He and his buddy Dale Villasenor flew throughout the nation simply to observe Sport 4 in Boston. They every spent $2,500 to sit down within the loge part. Velasquez, a lifelong Golden State fan, mentioned he tries by no means to overlook a house sport in individual.

The fan base isn’t at a crossroads fairly but. Curry, 34, hasn’t mentioned something about retiring, and Golden State could find yourself successful this collection. It’s tied, 2-2, with Sport 5 on Monday.

The opposite two stars of the core, Draymond Inexperienced and Klay Thompson, are simply 32. However age creeps up on all of us — and in basketball years, the three of them are someplace between middle-aged and eligible for Social Safety. There doubtless aren’t many runs left with these gamers acting at an elite degree.

Villasenor, 49, a dentist from Walnut Creek, Calif., recalled what life as a Golden State fan was like earlier than Curry was drafted with the seventh decide in 2009, again when the crew performed at Oracle Enviornment in Oakland as a substitute of the Chase Heart in San Francisco.

We used to observe video games the place we might simply go hang around and simply look ahead to All-Stars to come back by,” Villasenor mentioned.

Now, Golden State is the draw. Often, when Golden State performs street video games, a big contingent of its followers reveals up. The crew is among the many N.B.A. leaders in street attendance. Generally, it’s a matter of getting one of many world’s largest stars in your crew in Curry, a high jersey vendor.

In Boston, nonetheless, a metropolis with a storied basketball historical past, street jerseys had been tougher to identify on Friday night time. Making an attempt to find a Golden State fan was like enjoying The place’s Waldo? however for specks of gold and blue as a substitute of Waldo’s crimson and white. Each seat within the area was draped with a white-and-green shirt from the Celtics that mentioned, “It’s All About 18,” a reference to Boston’s pursuit of an 18th championship.

This N.B.A. finals is a distinction in legacies. Golden State has received six titles — three of them prior to now seven years. Its dominance has largely been within the twenty first century, whereas the Celtics are steeped in nostalgia — wistful for the times of Invoice Russell and Larry Chicken, with just one championship since 1986.

This has created totally different reputations for the supporters of every franchise. Latest success, as Chris Swartzentruber, 30, an insurance coverage agent from Kalona, Iowa, put it, invitations current followers.

“I don’t know any bandwagon Celtics followers,” he mentioned. “I do know plenty of bandwagon Warriors followers.”

Not that Swartzentruber is the purest fan himself. He mentioned he roots just for Thompson, not the crew. He has adopted the crew to a number of finals video games since 2015 to observe him play, and, as anticipated, he was donning a Thompson jersey to absorb Sport 4. For this journey, he traveled from Kalona by himself to sit down courtside. His ticket price $3,500. His fandom stems partly from being a robust shooter himself rising up.

I don’t spend that a lot cash,” Swartzentruber mentioned. “That is my trip, and I haven’t had a trip in, like, three years.”

And since sport fandom is an irrational enterprise, it invitations some amusing allegiances and profane habits. That is particularly the case in Boston, the place followers are recognized to be — let’s name it, expressive. The Celtics’ fan habits has change into a narrative on this collection due to Sport 3, when followers chanted vulgarities at Inexperienced.

N.B.A. Commissioner Adam Silver was requested for his response to fan chants by a neighborhood reporter in Boston.

“I would like followers to get pleasure from themselves,” Silver mentioned. “After all, because the league workplace, you need to see it completed with respect for all of the members, however I get it. I like the vitality that Boston followers deliver.”

If Silver’s large smile may speak, it might need added: “Boston, please don’t be mad at me. Did I point out I like clam chowder?”

Nancy DeBlasio, 41, attended the sport from Berlin, Conn., together with her girlfriend, Ashley Cialfi, 33. Each of them wore blue-and-yellow Golden State T-shirts. DeBlasio is a instructor and a basketball coach rooting for Curry. DeBlasio mentioned that being on the streets of Boston together with her T-shirt had been “fairly brutal,” however that the 2 of them had been “taking it as a result of we perceive.”

“I believe it’d be worse if we had been guys,” Cialfi chimed in.

“Oh, most positively,” DeBlasio concurred.

Actually? However why?

“As a result of they’re going to go straightforward on some chicks,” Cialfi mentioned.

However then got here a pro-wrestling-style plot twist: DeBlasio mentioned she is definitely a Celtics fan, however concurrently a Curry fan. She insisted that regardless of her shirt, she was truly rooting for a Boston win. (“No, you’re not,” Cialfi knowledgeable her.) No epithets had been thrown in that trade.

Nor had been they thrown close to Andy and Ryan Malburg, a father and son who had pushed virtually seven hours from Buffalo for the sport. Ryan, 15, who virtually cried when he discovered in regards to the tickets, was a lifelong Golden State fan attending his first N.B.A. sport.

OK, truthful level: What’s “lifelong” if you’re 15?

However this implies Ryan’s technology of Golden State followers is spoiled: He has largely recognized successful, which made his reference to the crew as a “good, up-and-coming crew proper now” comprehensible. (Andy and Ryan are additionally Buffalo Payments followers, so it evens out.) Ryan’s father, in the meantime, made clear that the Malburgs wouldn’t be collaborating in any profanity-related excessive jinks initiated by rude Boston followers.

“He is aware of to be respectful, and he is not going to say any of these issues,” Andy Malburg, 43, sternly mentioned. “I can assure you that.”

Certain sufficient, Celtics followers chanted once more at Inexperienced all through the sport and infrequently even cursed at Thompson. However finally, it was the Golden State followers who left the sector glad. Curry placed on a classic efficiency, scoring 43 factors. As a substitute of mortality, Curry had backers of each groups awed by the newest marketing campaign to enshrine himself in basketball immortality.

“It doesn’t get any higher than this,” Velasquez mentioned after the sport, “popping out to the East Coast to observe the Boston Celtics, traditionally top-of-the-line franchises.”

“The Boston Celtics,” Villasenor exuberantly interrupted.

“I do know!” Velasquez mentioned, matching his jubilance. “To beat them at their dwelling court docket!”

As they spoke, a person who seemed to be in his 20s and sporting a Celtics jersey approached and seen their Golden State apparel.

“You guys are bums, you recognize that?” the person mentioned, unprompted. It was certainly one of a number of opinions associated to the crew he needed to get off his chest.

As he closed out his eloquent soliloquy, the person rotated and did a dance — together with his personal bum gyrating towards Velasquez and Villasenor.

“Eh,” Villasenor mentioned of Celtics followers, sarcastically. “Truthfully, stylish.”
