Cannons Lacrosse Club

The Cannons won the Steinfeld Cup for the first time in 2011, defeating the Hamilton Nationals 10–9. Boston went 9–3 in the regular season, their best record since going 10–2 in 2005. After losing to Chesapeake 13–9 in the 2010 semifinal, the Cannons avenged the Bayhawks by defeating them 14–13 in the 2011 semifinal with a goal from Max Quinzani. Boston became the fifth charter franchise to win a championship. By 2011, the Cannons were one of four charter franchises still in the league that started with six teams in 2001. The other three remaining charter franchises (Lizards, Bayhawks, and Rattlers had all previously won at least one Steinfeld Cup (The defunct Barrage had won three). Head coach Bill Daye stepped down a month after winning the Steinfeld Cup, citing he wanted to spend more time with his family.[3] As of 2016, Daye is still the franchise's all-time leader in coaching victories with 43 and the only head coach with multiple playoff victories.

The Cannons in 2013 and 2014 finished 5–9 and 6–8. This included a 1–5 start in 2013 leading to Steve Duffy's firing on June 10.[4] John Tucker took his place and played .500 for the rest of the season. After the Cannons missed the playoffs for the fourth time in franchise history in 2014, Tucker led the team back to the postseason in 2015 as the 8–6 fourth seed. They played the New York Lizards and lost 16–15 in overtime. The Lizards went on to win the Steinfeld Cup.

John Tucker left the Cannons after the 2015 season to become the first head coach and general manager of the expansion team Atlanta Blaze. On October 8, 2015, Sean Quirk was announced as the sixth head coach in franchise history.[5] In an odd 2016 year in which seven of the league's nine teams, including the Cannons, finished with identical 8-6 records, Quirk's team was not rewarded with one of the four playoff spots after tie-breaking procedures. On December 20, 2016, it was announced that John Tucker would be returning to the Cannons as the team's offensive coordinator in 2017.[6] Tucker was fired mid-season by the Blaze after a 3–7 start.

Despite a Week 1 win in 2017, the Cannons season turned around. At 3–6, the Cannons traded away captain Will Manny and Joe LoCascio to the New York Lizards for Dave Lawson and Chris LaPierre on June 27.[7] On July 14, the Cannons announced that neither Lawson nor LaPierre would suit up for the team that season. Dave Lawson informed team officials that he would be retiring from the league while Chris LaPierre decided not to report to the team.[8] The Cannons finished the season on a six-game losing streak. At 3-11, the Cannons posted the worst record in the league and tied their franchise-worst record from 2001, their inaugural season.

Following the 2018 season, Paul Rabil launched the Premier Lacrosse League, baiting over 140 MLL players to migrate over. However, the Cannons maintained more of their roster than other teams like the Dallas Rattlers or Rabil's New York Lizards.[9] Two months prior to the start of the 2019 season, the league cut the team roster from nine to six when the Ohio Machine and Florida Launch folded and Charlotte Hounds suspended operations for two seasons.[10] Taking this to their advantage, the Cannons posted a 9–7 record in 2019, good enough for the third of four postseason seeds and gave Boston its first playoff berth since 2015. Boston faced the Denver Outlaws in the semifinal, who were also hosting Championship Weekend. The Cannons got off to a hot start and led by as many as six goals, but ultimately fell, 17–15, ending their season.[11]

2019 was the Cannons' first season in Quincy. During the offseason they announced a move to and $1.5 million renovation of Veterans Memorial Stadium.[12] The Cannons announced two sellouts in their first season in the updated venue.

Due to the COVID-19 pandemic, the 2020 season was shortened to five regular season games in seven days, all to be played in front of no fans at Navy-Marine Corps Memorial Stadium in Annapolis, Maryland. The Cannons finished fourth place out of six teams with a 3–2 record, and were the only team to defeat the Denver Outlaws in the regular season. Heading into the postseason, the Cannons were scheduled to play the Outlaws in the semifinal. However, after a player from the Chesapeake Bayhawks experience symptoms of COVID-19 and eventually tested positive, the two other postseason competitors, Chesapeake and Connecticut, withdrew from the tournament. The Cannons' semifinal game with the Outlaws was pushed back a day and would be played as the championship. Boston defeated Denver for the second time in two days, the latter in 13-10 fashion for the franchise's second title, first in nine years.[13] Newcomer attackman Bryce Wasserman, who played for the Dallas Rattlers the season before, was named league MVP for 2020.

On December 16, 2020, in a statement from Major League Lacrosse (MLL), the Boston Cannons officially became the 8th team in the Premier Lacrosse League (PLL). To fit league nomenclature, the team would be dropping "Boston" from their name and become "Cannons Lacrosse Club." Their roster will be set via expansion draft, and the team will begin play in the PLL in the 2021 season. Small tweaks to the former Boston Cannons resulted in a PLL crest and logo reveal on January 12.[14] One week later, the league announced Sean Quirk would continue coaching at the helm of the Cannons identity.[15]
