I love y'allThe one guy I wanted to keep smh
They literally on national TV reminding us every broadcast that he was traded from Chicago smh

All good, I had been saying it for years... The Bulls having Coby and Ayo on discount deals and still being sorry was like a NFL team hitting on a QB for cheap and having a good 3 to 4 years to build out the rest of the roster and just not doing it.I love y'all![]()

As Moneyball—a data-driven approach to evaluate players—further infiltrated professional sports, Lewin noted franchises’ rising interest in “quantitatively oriented” individuals and shared his work with Addona to generate opportunities with NBA teams. He landed summer internships with the Cleveland Cavaliers in 2007 and 2008, supporting a front office eager to create meaning out of basketball data and capitalize on the generational talent of a young LeBron James.
Back at Mac, meanwhile, Lewin traded the gridiron for the hardwood as his fascination with basketball swelled. He earned a spot on the basketball team and his two years as a reserve guard with the Scots delivered a heightened knowledge of the game’s tactics and schemes, which only sharpened his analytics work.
“When I think of Dave, the first word that comes to mind is brilliance,” says Abe Woldeslassie ’08, Mac’s current head basketball coach and Lewin’s former teammate. “He was thinking about basketball stats in a way few others were back then.”
Over the last dozen years, Lewin has filled a variety of roles for the Celtics related to scouting, salary cap, strategy, and analytics. He also had a three-year stint as general manager of the Celtics’ G-League (minor league) team, the Maine Red Claws. There, given an organizational edict to find the best up-and-coming coaches, he was a part of hiring a young assistant coach from tiny Fairmont State University. Eight years later, that coach, Joe Mazzulla, steered the Celtics to a league-leading eighteenth championship.
A naturally competitive person, Lewin relishes the challenge of trying to build the best possible team within the constraints of the NBA salary cap, one intentionally designed to promote parity. He spends his days collecting insights from coaches, players, scouts, and other front office peers and poring over spreadsheets of player information—a vital grind to ensure the Celtics possess every ounce of information necessary to make shrewd personnel decisions in the draft, free agency, and trade market.
“My job is a lot like the class you take in college in which the entire grade is the final exam,” says Lewin, who was promoted to assistant general manager in 2022. “You prepare for the big decisions over months and years, but all anyone will care about is whether you get those couple of big decisions a year right.”
Given the Celtics’ success over the last dozen years—six Eastern Conference Finals appearances, two NBA Finals runs, and one title—Lewin enjoys stability rare to find in pro sports. He’s also earned accelerating attention. In August, The Athletic named Lewin to its list of forty prominent NBA coaches, executives, managers, and influencers under age forty, and his name frequently arises when front office positions open elsewhere around the NBA.
