B. J. Neufeld

Team Koe started their 2019–20 season at the 2019 AMJ Campbell Shorty Jenkins Classic and lost in the quarterfinal to Brad Jacobs. They lost the final of the Stu Sells Toronto Tankard to the Jacobs rink as well. In Grand Slam play, they made the semifinal of the Tour Challenge and the quarterfinals of the National. They missed the playoffs at both the Masters and the Canadian Open. At the Canada Cup, they finished the round robin with a 5–1, which qualified them for the final which they lost to John Epping. At the 2020 Tim Hortons Brier they finished the championship pool with a 7–4 record, which was a four way tie for fourth. They faced Jacobs in the first round of tiebreakers where they lost 8–3 and were eliminated. It would be the team's last event of the season as both the Players' Championship and the Champions Cup Grand Slam events were cancelled due to the COVID-19 pandemic. On March 16, 2020, Team Koe announced they would be parting ways with second Colton Flasch. The following day, the team announced they would be adding John Morris to the team as their new second.

While competing at the 2018 Viterra Championship, McEwen came down with chickenpox and was unable to play after the first game. Neufeld skipped the team, until a surprise appearance by McEwen in the final where they would lose to Carruthers. Despite the setback, his rink still had a chance to qualify for the 2018 Tim Hortons Brier through the wildcard game, which he won over Jason Gunnlaugson. The team had a difficult Brier and alongside Carruthers was unable to qualify for the playoffs. Following the disappointment at the Brier the McEwen team announced they would be breaking up at the end of the 2017-18 season. Just days after the announcement the McEwen team won the 2018 Elite 10 Grand Slam of Curling event, winning the top $28,000 prize money, and was the first team to go through the entire event undefeated. The Grand Slam victory was the team's seventh overall.

Neufeld joined the Calgary based team of Kevin Koe, Colton Flasch and Ben Hebert the following season. His new team began the 2018-19 curling season by winning the first leg of the Curling World Cup, defeating Norway's Steffen Walstad in the final. In provincial playdowns, the Koe rink lost two of their first three games at the 2019 Boston Pizza Cup, before winning five straight games to claim the Alberta championship. The team represented Alberta at the 2019 Tim Hortons Brier, and went undefeated in the entire tournament en route to winning his first Brier title. They went on to represent Canada at the 2019 World Men's Curling Championship, finishing the round robin with a 9-3 record. They battled through the playoffs to play Team Sweden's Niklas Edin rink in the final, losing 7-2. In Grand Slam play, the team failed to win any slams, but did make it to three finals. Despite the lack of any event wins, their strong play was good enough to award them with the Pinty's Cup for the season's best Slam team. The team ended the season in the Grand Final of the Curling World Cup, where they beat the host Chinese team (Zou Qiang). At the end of the season, Team Koe ranked first on the World Curling Tour Order of Merit and Money List. This also meant they led the CTRS standings, finishing the season with 512.335 points.

In 2017 the McEwen rink would defend their Manitoba Championship Title by beating Reid Carruthers in the final. He would then better his 2016 Brier showing, going 9-2 in the round robin to enter the playoffs in 1st place and with hammer and choice of rocks (Brad Gushue would also be 9-2 but would lose 1st place due to losing his round robin meeting). They would fall 7-5 to Brad Gushue in the 1-2 game however. In the semi finals against reigning Brier and World Champion Kevin Koe, Manitoba was in control almost the whole way but up 5-3 with hammer in the 8th end Koe would make an incredible comeback with a steal in the 8th, a two in the 10th, and another steal in the extra end, dropping Manitoba to the bronze medal game. They would recover from this disappointment to win his first Brier medal, defeating Brad Jacobs in their rematch of the 2016 bronze medal game, 7-6 in an extra end.

The McEwen rink would win their first provincial title in 2016, sending them to their first Brier. The team had already booked their place to the 2016 Tim Hortons Brier as their opponents, the Matt Dunstone rink had committed themselves to the 2016 World Junior Curling Championships which occurred at the same time as the Brier. When the Dunstone rink beat Reid Carruthers in the semi-final this meant that McEwen's team would go to the Brier, even if they had lost to Dunstone.

Despite being ranked first in the world on both the World Curling Tour Order of Merit rankings and on the WCT money list, McEwen lost his fifth provincial final in six years in 2015, losing to Reid Carruthers.

The team continued their strong season that year by defeating provincial rival Stoughton in the semi-final of the 2011 Canadian Open. They would then go on to beat the Glenn Howard team in the extra end of the final, thus winning their second career Grand Slam and their second of that season.

Neufeld's rink once again made it to the Manitoba provincial this time, being the top seed (also ranked 1st in Canada). However, once again lost to Stoughton in the final of the 2011 Safeway Championship, losing by one point in the final end. The McEwen team then lost their third straight provincial final game at the 2012 Safeway Championship, this time losing to Rob Fowler, thus tying a provincial record for consecutive final losses previous set by Kerry Burtnyk from 97-99. This dubious record was avoided in 2013, when the McEwen rink failed to reach the final, but again losing to the rival Stoughton rink in the 2013 Safeway Championship semi-final. Once again, at the 2014 Safeway Championship, the team lost the final to Stoughton.

Neufeld made it to his first provincial final in 2010, when he lost to Jeff Stoughton in the 2010 Manitoba provincial final. The game was being played in Steinbach, Manitoba and as the Neufeld brothers and their father have roots in Steinbach, they were treated very much as the home team and crowd favourites.

The McEwen rink started the 2010-11 season off well by defeating provincial rival Jeff Stoughton to win the World Cup of Curling and his first ever Grand Slam title in November, 2010. In part of the teams runner-up result in the provincial finals of 2010 and in part because of his 4 victories and leading the overall money winnings in the World Curling Tour season as of November 2010, the McEwen team was named as a nominee for the provincial team of the year by the Manitoba Sportswriters and Sportscasters Association.

During the 'Road to the Roar' 2009 Olympic Qualifier, the McEwen team just lost out to fellow Manitobans the Jason Gunnlaugson team in the semi-finals. Neufeld thus missed out on the 2009 Canadian Olympic Curling Trials final despite being the favourite in that particular matchup vs Gunnlaugson.

At the conclusion of the 2008-09 season the McEwen team was ranked 7th on the CCA rankings. They had made it to three Grand Slam playoffs, and finished 4th at the 2009 Safeway Championship.

Neufeld joined the team of Mike McEwen and Matt Wozniak in 2007 with his brother Denni. In their first season together, they were a semi-finalist at the 2008 Safeway Championship, Manitoba's provincial championship. Their first Grand Slam event as a team was at the end season, at the 2008 Players' Championships. The team won two games, before being eliminated.

As a junior curler, Neufeld was a three-time provincial junior champion of Manitoba in 2004, 2005, and 2007. He finished as a national junior semi-finalist at the 2004 Canadian Junior Curling Championships.

Brendan "B. J." Neufeld (born February 28, 1986) is a Canadian curler from Winnipeg, Manitoba. Neufeld plays third for the Kevin Koe rink. He started curling around the age of ten and, like older brother Denni Neufeld, cites the achievements of his father as leading his interest into the game of curling. His father is Chris Neufeld who was a three-time Manitoba curling champion and one time Labatt Brier champion in 1992 as part of the Vic Peters team.
