Boston Celtics forward Jaylen Brown could well have as much untapped talent as any young player in the NBA. He was brought along slowly in his first year in Boston and has not had the opportunity to show his full potential as the Celtics have stocked the roster with free-agent talent like Kyrie Irving and Gordon Hayward (along with, now, Kemba Walker).
That makes the next four weeks somewhat awkward for Brown and the Celtics, who have until October 21 to agree to a contract extension. According to a league source, “the chance is pretty slim” that Brown signs a long-term deal with the team in the coming month. Around the league, the expectation is that Brown and the Celtics won’t come to a deal.
Brown would still be under contract for this season, at $6.5 million (that would be the case even with the extension). He would become a restricted free agent next summer, which means Boston would still control his rights and be able to match any contract offer he received.
