On Sunday night at Klöckner Stadium, the No. 5-seeded Virginia Cavaliers, the host school of this year’s NCAA Men’s Lacrosse Championship Weekend just up the hill at Scott Stadium, lost 14-10 in the first round of the NCAA Tournament to an unseeded Georgetown team. The campaign-ending defeat means Memorial Day in Charlottesville will be a championship someone else plays for.
Listen Here:
Three years ago, this would have been unthinkable. In Sean Kirwan’s final season as Virginia’s offensive coordinator in 2023, the Cavaliers led the nation at 17.24 goals per game, set a program scoring record with 293 goals, and broke an assists record that had stood since 2006. They were two years removed from a national title and one year removed from another Final Four. The program was operating like a machine.
Then Kirwan left for Dartmouth. And the machine has been coming apart ever since.
The drop, in three acts
2024. Virginia made it back to Championship Weekend, its fourth Final Four in five years, with an attack line that featured Connor Shellenberger, who would finish his career as the ACC’s all-time assists leader; Payton Cormier, who would graduate as the NCAA’s all-time leading goal scorer; and a record-setting freshman in McCabe Millon. They lost to Maryland 12-6 in the semifinal. Six goals, from a team with that much firepower, on that stage. The postmortem inside the lacrosse media was direct: the loss of Kirwan, while less talked about than the headline graduations to come, had been quietly costly.
2025. The Cavaliers missed the NCAA Tournament for the first time in Lars Tiffany’s tenure. After a strong non-conference run, ACC play unraveled them, with three straight conference losses to close the regular season followed by a blowout exit from the ACC semifinals against Notre Dame. For a program that had played on Memorial Day weekend in four of Tiffany’s previous five eligible postseasons, it was a stunning omission.
2026. A bounce-back regular season, an ACC Tournament championship that vaulted them to a No. 5 seed in the NCAA bracket, and then the home loss to Georgetown. Final record: 10-7. The Hoyas, Big East champions but unseeded, got hat tricks from Jack Schubert, Jack Ransom, and Rory Connor and never let the Cavaliers back into the second half.
Three years, three steps down: from Final Four to no tournament to first-round exit at home. All while Kevin Cassese, hired from a 16-year head-coaching tenure at Lehigh, has run the Virginia offense in Kirwan’s place.
Who Sean Kirwan actually is
Kirwan is not a journeyman climbing the coaching ladder. By any honest measurement of college lacrosse offense over the last fifteen years, he is the most productive offensive mind in the sport at any level.
He came out of Mountain Lakes, New Jersey, one of the country’s most decorated high school lacrosse towns, and went to Tufts because the Ivy League schools he wanted didn’t recruit him. He won a national championship there as a sophomore in 2010, which was Tufts’ first national title in any sport. He made it back to the title game the next year, set the program’s single-season (66) and career (150) goal-scoring records, and was a two-time All-American and Academic All-American.
When he graduated in 2012, head coach Mike Daly kept him on staff. In 2014, Kirwan’s second year running the offense, Tufts won the NCAA Division III national championship and put up 423 goals. That was, at the time, the highest single-season goal total ever recorded by a college lacrosse team at any NCAA division. The Jumbos also led the country in assists. Three Tufts players cleared 100 points apiece that season, which had never happened on one team in NCAA history.
Then Lars Tiffany hired him at Brown in 2014, and the offensive numbers traveled with him. In 2016, the Bears scored 310 goals and led the nation at 16.32 per game, still the third-highest single-season scoring output in Division I history. Brown made the Final Four. Dylan Molloy won the Tewaaraton Trophy, the first in program history. Brown won the Ivy League both seasons Kirwan was on staff.
In 2016, Tiffany was hired at Virginia, and Kirwan and goalie coach Kip Turner went with him. Over seven seasons in Charlottesville, his Cavalier offense won two national championships (2019 and 2021), finished top-three nationally in scoring four times, coached 18 All-Americans, produced consecutive ACC Rookies of the Year in Michael Kraus and Matt Moore, developed three-time first-team All-American Connor Shellenberger, and set the program record for goals in a season in his final year.
Kirwan won the IMLCA’s Division I Assistant Coach of the Year award in 2021.
The case that the offense was him
You can argue talent. Tufts had Cole Bailey, Chris Schoenhut, and Beau Wood. Brown had Molloy. Virginia had Shellenberger, Cormier, Moore, and Kraus. Any offensive coordinator looks brilliant with rosters like those.
The harder argument to dismiss is that the offense was elite the year Kirwan arrived at every program. A Division III team that had been good but not historic became the highest-scoring team in NCAA history. A Brown program that hadn’t been in the Final Four in over a decade got there immediately. A Virginia program coming off four consecutive disappointing seasons under Dom Starsia won a national title in Kirwan’s third year. The system did not need a recruiting cycle. It worked immediately at three different programs across two divisions.
And here is the inversion worth sitting with: in 2023, Kirwan’s final year, Virginia scored 293 goals, a school record. In 2024, with most of the same roster minus Kirwan, the program could not score more than six goals in its season-defining game.
Tiffany himself, when Kirwan left, credited nearly a decade of strategic conversations with Kirwan for raising his own coaching IQ. It was a generous quote at the time that has aged into something more uncomfortable.
The honest counterargument
It would be lazy not to acknowledge what else changed.
Shellenberger graduated. Cormier graduated. Cole Kastner graduated. Those three accounted for 228 of Virginia’s 403 points in 2024. No program, anywhere, replaces an all-time NCAA goal scorer and an all-time ACC assist leader at once and pretends it didn’t.
Kevin Cassese is not a token replacement. He ran the Lehigh program for 16 years and brought legitimate offensive credentials with him. The 2024 Virginia offense was statistically still very good. The 2026 ACC Tournament title was a real accomplishment in a deep league.
And the broader competitive landscape has shifted: Cornell won the 2025 national title, Maryland and Notre Dame have stockpiled talent, and the ACC is arguably the deepest conference in the sport.
So the cleanest version of the thesis isn’t that Kirwan’s departure caused everything. It’s that his departure removed the one element that consistently outperformed the talent around it. That claim is much harder to dismiss.
What Kirwan is building in Hanover
Dartmouth, when he took it over, had gone 25-71 since 2015 under Brendan Callahan. The Big Green had not appeared in the NCAA Tournament since 2003.
In his second year, Dartmouth went 8-5 with two Ivy League wins and broke into the Division I top 20. Year three, in 2026, finished 4-5 in a brutal Ivy schedule that included Cornell, Princeton, Penn, Yale, and Harvard. Three of those programs were ranked in the national top ten at various points this spring. Five-star recruits, players who would have signed with Princeton or Yale a few years ago, are committing to Hanover.
It isn’t a turnaround yet. It’s the early stages of one.
The poetry of the calendar
On March 23, 2026, Sean Kirwan walked back into Klöckner Stadium as the head coach of Dartmouth. The Cavaliers, on paper, were still the more talented team. They had won at Charlottesville on Memorial Day weekend in 2019 and 2021 with Kirwan calling their offense.
Six weeks later, that same Virginia program was eliminated from the NCAA Tournament on the same field, by Georgetown, while Scott Stadium, a five-minute drive away, prepared to host the national title game of a tournament without them in it.
Lars Tiffany is one of the great coaches in college lacrosse. The Cavaliers will recruit, retool, and contend again. The 2024 recruiting class was ranked No. 1 in the country. The pipeline is not broken.
But the last three years have laid down a pattern that is no longer easy to look past.
When Sean Kirwan left, something specific about Virginia lacrosse left with him. The 2024 box score said it first. The 2025 selection committee confirmed it. The 2026 first round made it impossible to ignore.
