The Grand Slam of Curling finds itself at a crossroads this week after a round-robin finale in Victoria descended into farce, prompting boos from the stands, accusations of collusion from a eliminated American side, and an emergency review by the circuit’s competition committee. In a match where a tie guaranteed both Canadian teams a playoff spot, skips Matt Dunstone and Brendan Bottcher engineered a passive final end that froze out Danny Casper’s U.S. rink, igniting a debate over whether the sport’s innovative scoring system has inadvertently incentivised gamesmanship over competition.
A Finish That ‘Looks Horrible’
The atmosphere inside the Save-On-Foods Memorial Centre turned toxic late Friday night. With both Team Dunstone and Team Bottcher sitting on six points in the standings, the mathematics were brutally simple: a regulation win was worth three points, but a shootout awarded two points to the winner and one to the loser. Seven points would secure a quarter-final berth; six would not.
When the eighth end began, the competitive fire evaporated. Dunstone’s lead, Ryan Harnden, drew the button with his first stone. Bottcher’s lead, Geoff Walker, responded by flashing his rock wide of the house — a miss that immediately drew scrutiny. From that moment, the end devolved into a series of deliberate throw-throughs and soft taps. Seconds Mark Nichols and Tanner Horgan both hurled their opening stones through the rings, prompting a chorus of jeers, chants of “Borrrr-ing!” and shouts of “Shame!” from the Victoria crowd.
“They’re on ESPN in the U.S. and Sportsnet in Canada, thousands of people are watching it, I’m sure, and it looks horrible,” Ben Richardson, Casper’s second, said in the aftermath. “It definitely leaves a bitter taste in my mouth. I can’t speak for all the people that watched it, but it’s definitely not a good look for our sport.”
The Mathematics of Mutual Assured Qualification
The controversy centres on the Grand Slam’s 3-2-1-0 scoring structure, now in its second season. Designed to encourage aggressive play by devaluing a shootout loss relative to a regulation win, the system instead created a unique prisoner’s dilemma in Victoria. Because both Canadian rinks entered the final draw with identical records, a tied game — and the resulting shootout — mathematically guaranteed advancement for both.
Casper, sitting one point back, needed a decisive result in the Dunstone-Bottcher match to force a tiebreaker scenario. Instead, they were forced to watch from the sidelines as the two Canadian teams effectively played out a pre-arranged conclusion.
Luc Violette, Casper’s third, offered a technical dissection of the final end that suggested the play was not merely risk-averse, but actively co-operative. He noted that after Walker’s initial flash, Harnden’s second stone stopped gently at the top of the four-foot. Walker then executed a double takeout that rolled out, leaving the house open.
“You would always see a team throw a corner guard in that situation if they were trying to maximize their odds of winning the game outright,” Violette said. He argued Harnden should have followed with a tight centre guard. “Instead, they lobbed one right on top of it to leave an easy double.”
The broadcast team read the room in real time. “Both of these teams, if this game goes to a shootout, will get into the playoffs,” host John Cullen said on air. “This looks like maybe a bit of a handshake agreement that both teams are saying, ‘Let’s do it.’” Analyst Brent Laing, a two-time Olympic medallist, pushed back on the collusion narrative but confirmed the strategic reality. “I doubt that there’s any agreement,” Laing replied. “I think they’re both just smart enough to know there’s no need to take on any risk, and the other guy thinks the same thing.”
‘No Conversation Whatsoever’
In the cold light of day, both skips denied any verbal pact. Dunstone, reached by phone, was blunt. “There was no conversation whatsoever. It was just how the scoreboard played out.” Bottcher, responding via text message, pointed to the specific sequence of play. “In eight, they threw a rock in the house and Geoff’s first rock picked. That said, our team knew we needed a point to qualify given the format.”
The distinction between an explicit agreement and a tacit understanding is thin, and for Nic Sulsky, CEO of The Curling Group which owns the Grand Slam, the optics were damaging regardless of intent. “It was a little too obvious, it was a little too raw,” Sulsky admitted. “And I feel for the Casper boys. But at the end of the day, fans are in the stands watching rocks being thrown through the house. I’m not a supporter of that in a situation like Friday night.”
Sulsky confirmed the seven-member competition committee — comprising players, coaches, and management — was scheduled to meet Thursday or Friday to dissect the incident. The review comes at a delicate time for a tour trying to expand its global footprint and television appeal.
The Fallout and the Format
The irony was not lost on the participants. Having secured their playoff spots through the shootout — Dunstone winning 6-5 to claim two points, Bottcher taking one for the loss — both Canadian teams were eliminated in the quarter-finals. Dunstone fell to Switzerland’s Yannick Schwaller, the eventual champion, while Bottcher dropped a decision to Brad Jacobs.
“This isn’t why we didn’t win this weekend,” Violette conceded. “But at the same time, if this were another sport, I do think there would be some sort of sanction or something that happens as a result of a scenario like we saw play out. I feel like this was, I guess, a step back in us feeling confident in the integrity among teams at our highest level.”
The circuit moves quickly. The next stop is the GSOC Masters in Medicine Hat, Alberta, running November 3-8. But the spotlight will remain on the competition committee’s findings. The 3-2-1-0 system was introduced to solve a different problem: the prevalence of conservative, blank-end hockey scores in the traditional win-loss format. By rewarding regulation wins disproportionately, the architects hoped to force teams to chase victories rather than settle for shootout lotteries.
In Victoria, the incentive structure backfired spectacularly. The format didn’t just fail to prevent a dead rubber; it manufactured one.
Why it Matters
Curling has long traded on a reputation for sportsmanship so ingrained it is codified as the “Spirit of Curling” — a gentleman’s agreement that players police themselves and concede when beaten. The events in Victoria didn’t technically break a rule, but they shattered that unwritten code, exposing a structural flaw that rewards mathematical certainty over competitive instinct. If the Grand Slam cannot trust its elite athletes to compete rather than calculate, the product risks becoming unwatchable for the casual fans the tour desperately needs to attract. The committee’s response this week will define whether the 3-2-1-0 experiment is a failed innovation or a teething problem with a legislative fix.
