From the mountaintop, after the Boston Celtics won the 2024 championship, Jaylen Brown emphasized how much it meant to win a ring alongside teammate Jayson Tatum after all they had experienced together.“We’ve been through a lot, the losses, the expectations,” Brown said. “The media have said all different types of things: We can’t play together, we are never going to win. We heard it all. But we just blocked it out, and we just kept going. I trusted him. He trusted me. And we did it together.”Two years after that triumphant moment, the Celtics are splitting up one of the most successful duos in recent history. In a shocking move, the Celtics have agreed to trade Brown to the Philadelphia 76ers for Paul George, a league source confirmed to The Athletic. The 76ers are also sending the Celtics two first-round picks and two second-round picks in the deal, according to a league source who was granted anonymity because the deal isn’t official yet. ESPN first reported the move.The third pick in 2016, Brown did little but win in Boston, reaching the playoffs in each of his 10 seasons with the team. No other franchise won more playoff games than the Celtics did during Brown’s tenure. With him, they advanced to the conference finals six times and the NBA Finals twice. He won the 2024 NBA Finals MVP award while helping the team end a 16-year championship drought. The Celtics were expected to experience a significant falloff after serious changes last offseason, but, with determined leadership and career-best production, Brown helped them defy expectations throughout a 56-win regular season.
