There may be, quite simply, no place in America less Jewish than Brigham Young University’s football stadium on Yom Kippur. In a typical year, few of the roughly 63,000 fans who streamed into LaVell Edwards Stadium in Provo, Utah, for the annual homecoming game would even be aware that Saturday was the holiest day on the Jewish calendar. But this is no typical year: The star quarterback for BYU, Jake Retzlaff, is Jewish. And he has led the team for the flagship Mormon university to an undefeated start that’s confounded prognosticators and propelled the Cougars to a top-15 national ranking.

It is one of those wonderfully strange college-sports stories that serves as a magnet for camera crews. In recent weeks, ESPN and CBS have both turned up on campus to profile Retzlaff, and Fox Sports dispatched a team of 140 to broadcast its game-day studio show from Provo. The stakes for Saturday’s game were high—a win against the University of Arizona Wildcats would not only make the Cougars bowl-eligible, but keep the team’s chances at a Big 12 championship and national-playoff berth alive.

The stakes were also high for me personally. As a dad gradually surrendering to stereotype in my approach to middle age, I had recently embarked on a mission to indoctrinate my young kids in the college-sports fandom of my alma mater. I bought them overpriced royal-blue hats and sweatshirts, and showed them viral videos of the beloved Cougar mascot, Cosmo, doing TikTok dances and jumping through hoops of fire. After deciding I would bring them to Provo last week for their first BYU football game, I spent days teaching them the fight song. By the time we took our seats on Saturday afternoon, the propaganda had done its work—they couldn’t wait to belt out “Rise and shout, the Cougars are out” after each BYU touchdown.

I assured them they’d have many opportunities to sing, but I secretly had my doubts. Arizona’s defense was good; BYU’s first five wins of the season had been weird and a bit fluky. Most important, like any BYU fan, I harbored a vaguely superstitious notion that this was the point of the season—with national hype peaking and people finally taking notice—that our team usually melts down. Chatting with fans before the game, I discovered I wasn’t alone in this anxiety. One fan even wondered aloud if Retzlaff’s decision to play on Yom Kippur, which many religious Jews spend in prayer and fasting, would curse his performance. He was joking, I thought. But then the Cougars’ opening drive ended with Retzlaff missing an open receiver in the end zone on fourth down, and the Wildcats marched down the field to score, and suddenly the specter of divine punishment didn’t seem quite so far-fetched. I found myself wondering if any other nervous BYU fans were Googling How bad is it to play football on the day of atonement?

When I met Retzlaff on campus a couple of days later, I told him about the earnest Mormon’s concern over his compliance with Jewish law, and he laughed. “That’s fandom,” he told me. Retzlaff, who wore sweats and a Star of David necklace, said he never seriously considered skipping the game. He knew some Jews would disagree—Sandy Koufax famously sat out the first game of the World Series in 1965 to observe Yom Kippur. But to Retzlaff, playing on Saturday was a chance to represent his faith on a stage that is not exactly teeming with people like him. Utah has one of the smallest Jewish populations in America, and at BYU, there are only two other Jewish students. That puts Retzlaff in a strange position: He represents one of the university’s smallest minorities and is also one of its most famous students.

Retzlaff, a California native who spent two years as a top junior-college quarterback, told me that his first thought when BYU recruiters showed up was about football, not faith. The school has a comparatively high-profile program with a powerhouse pedigree—the Cougars won the national championship in 1984 and have churned out a string of famous quarterbacks over the years, including Steve Young and Jim McMahon. But he admits that contemplating what his non-football life would look like on a 99 percent Mormon campus gave him pause.

BYU, which strictly prohibits drinking, premarital sex, and a host of other traditional college pastimes, is not an obvious draw for most non-Mormon students. But every year, the school attracts a combination of college athletes who want to play their sport without distraction and students from other orthodox-religious backgrounds who don’t mind spending time on America’s most “stone-cold sober” campus. (Last year, a Muslim basketball player for BYU named Aly Khalifa made headlines for fasting during a March Madness game that fell during Ramadan.)

Retzlaff told me his arrival in Provo was a culture shock. Sundays were brutal: Local businesses closed, the campus shut down, and, with most of his teammates at church, Retzlaff found himself sitting alone in his room, struggling to ward off boredom. The mandatory religious classes, which frequently began with all the students singing a Mormon hymn, could also be disorienting. “Every single person around me has got this thing memorized,” he recalled, “and I have no idea what’s going on.”

Another player in his position might have chosen to downplay his religious differences; Retzlaff decided to lean in. On Instagram, he started referring to himself as the “BYJew,” and encouraged skittish friends and teammates to use the term as well. (Eventually, the Utah County Chabad began selling “BYJew” T-shirts.) To celebrate Sukkot last year, he arranged for a kosher food truck from Salt Lake City to visit campus so he could treat his teammates to shawarma and falafel. He relished the opportunity to educate. “Members of the LDS faith do have a funny fascination with Judaism,” he told me. Some of the questions he got—“Do you guys believe in Jesus?” for example—were rudimentary. (“To me, that’s like, you’ve never met a Jew in your life,” he told me.) But others were more sophisticated, prompting conversations about the overlapping theologies and shared cultural experiences of two religious minorities, one very old, the other relatively new.

The Latter-day Saint rituals weren’t his own, but Retzlaff learned to find comfort and even a kind of divine beauty in them. During the pregame team prayers, when all the other players bow their heads, he looks up and around the locker room at his friends and teammates—trying “to be present in the moment” as he reflects on his own gratitude.

Retzlaff’s experience took on a new dimension after the October 7 attacks on Israel last year. As campuses across America erupted in protests over the war in Gaza, and as many of those protests curdled into virulent anti-Semitism, Retzlaff was struck by how different his classmates seemed from the people in viral video clips hurling epithets at Jewish students. He suspected that the secularism that dominated those other campuses played a part. “I’d love to ask them about their faith,” Retzlaff told me of the protesters. “What are the odds that they’re faithful at all? I’d bet you they’re not.” For all the inconvenience and occasional awkwardness that BYU’s deep religious culture might cause him, Retzlaff believes it’s allowed his fellow students to see his Judaism not as a marker of political identity but as a faith that warrants respect, even reverence.

In fact, Retzlaff told me, as BYU’s quarterback he’s encountered more anti-Mormonism than anti-Semitism. The year before he joined the team, some fans at the University of Oregon greeted the Cougars with chants of “Fuck the Mormons.” The school eventually apologized, but Retzlaff told me he and his teammates have continued to face religious taunts in opposing stadiums. He’s less scandalized by the heckling than by the lack of outrage it seems to engender. “The blatant disrespect for their faith—it’s something to think about. What if there was a Jewish university that had a Jewish football team, and they were saying that in the stands?” Retzlaff asked me. “Like, imagine if that hit the papers. That would be a big deal.” The casual bigotry, and muted response to it, unnerves him. “There’s a lot of people who just don’t like Mormon people, for no reason,” he told me. “That’s what happened to the Jews all throughout history.”

In the arena on Saturday, Retzlaff and his team found their rhythm in the second quarter. After a perfect 20-yard touchdown pass tied the game, the Cougars never looked back. They scored 24 unanswered points, and forced four turnovers. We sang the fight song until our voices went hoarse, and by the time the game ended in a 41–19 blowout, my kids were converted. I had a Jewish quarterback to thank for helping me pass my fandom down to the next generation.

But BYU’s win wasn’t meaningful only to the Latter-day Saints who were watching that day. After the game ended, Retzlaff made his way to the locker room to shower and change, and then took questions at a press conference. Playing like that on Yom Kippur was, he would later tell me, a “spiritual experience.” He was exhausted and emotional. But before he could leave, he got word that someone was waiting for him in the stadium, now mostly empty. A Jewish fan had waited more than an hour to take a picture with the quarterback. After shaking Retzlaff’s hand and thanking him, the man said he was going home to break his fast.
