Ken Raymie built a nearly three-decade banking career in San Antonio, Texas, culminating in his tenure as president and chief executive officer of Generations Federal Credit Union from 2019 to 2024, following earlier leadership roles at Broadway National Bank, Transpecos Bank, and KeyBank. Under his guidance, Generations grew assets from $500 million to more than $750 million, achieved the highest annual net income in the credit union’s 83-year history, and streamlined operations from 15 branches to seven full-service locations. Raymie holds an economics degree from Boston University and a master of business administration from Northeastern University, and he has served on boards ranging from the American Heart Association to the Bexar County Sheriff’s Foundation. Away from the office, he stays active through basketball and golf, interests that make the following look at the Boston Celtics’ historic 2023-2024 offensive season a fitting companion piece.
The Boston Celtics rank among the most successful North American sports franchises. Since the team’s first season in 1946-1947, the Celtics have won 18 National Basketball Association (NBA) championships, more than any other organization. Boston teams have featured numerous Hall of Fame players, and the franchise has established numerous records.
In 2024, the Celtics won their 18th championship with one of the most efficient, high-powered offenses in league history. The Celtics won their 17th championship in 2008, following a more than two-decade drought.
That team featured a diverse scoring output from the likes of Paul Pierce, Kevin Garnett, and Ray Allen but was better known for its defensive prowess. Over the following seasons, the team remained a playoff staple, but the roster and offensive philosophy changed considerably, especially with the removal of head coach Doc Rivers in 2013 and the arrival of Brad Stevens.
Stevens instituted a modern, positionless offense based on space and pace. His playbook drew on an array of offensive systems, and he consistently maximized the skills of his personnel.
Perhaps no player benefited more from Stevens’ offense than undersized point guard Isaiah Thomas, who averaged 22.2 and 28.9 points per game during his two full seasons with the team, earning Most Valuable Player votes in 2016-2017 and finishing both seasons on the NBA All-Star team.
The Celtics began taking steps toward an 18th championship in 2016 by taking Jaylen Brown from Cal in the 2016 NBA Draft. The following summer, Boston selected Jayson Tatum out of Duke University as the third overall pick in the NBA Draft.
This young duo quickly flourished under Stevens’ dynamic offense, reaching the Eastern Conference Finals in 2017, 2018, and 2020. Stevens stepped away from coaching to join Boston’s front office, but the players did not miss a beat, advancing in 2022 to the NBA Finals, where they lost to the Golden State Warriors, and making the Eastern Conference Finals the following seasons.
During the 2023-2024 season, Boston’s roster, offensive scheme, and personnel came together as one of the most fluid offenses in NBA history. Led by Tatum and Brown, the team featured a bevy of skilled passers and two-way players, including Jrue Holiday, Al Horford, and Derrick White, along with valuable role players such as Kristaps Porziņģis and Payton Pritchard.
The Celtics attempted and made more three-point shots than any other team while ranking second in accuracy at 38.8 percent. They were the second-highest scoring team at 120.6 points per game, while allowing just 109.2 points from opponents, the fifth-best mark in the NBA.
Overall, the Celtics finished the season with a 64-18 record and a historic 123.2 offensive rating. The 2025-2026 Denver Nuggets rank second, with an offensive rating of 122.6.
The team’s blistering long-range shooting included five players who shot 40 percent or better from deep and five players averaging double-digit scoring, led by Tatum at 26.9 points and Brown at 23. Tatum finished the year with an All-NBA First Team selection, he and Brown were All-Stars, and both Holiday and White made the All-NBA Defense Second Team.
The team’s offensive prowess carried into the postseason. The Celtics cruised by the Miami Heat, Cleveland Cavaliers, and Indiana Pacers, dropping just two games en route to the NBA Finals.
A meeting with the Dallas Mavericks resulted in a five-game series victory and an 18th title for Boston, the perfect capstone for one of the greatest seasons in NBA history.
