That reality changes though this fall, as Brown is eligible to agree to a contract extension with Boston ahead of an October 21st deadline. A trio of notable first-round picks have already agreed to terms on a long-term pact with Ben Simmons and Jamal Murray (five-year max) setting the market and Caris LeVert (three years, $52 million) signing a more modest extension with the Brooklyn Nets. The Celtics have a lengthy track record (10 years) of not coming to terms on an extension with their first-round picks, and that’s a reality that Brown is very much aware of as he begins negotiations with Danny Ainge and company.
Brown confirmed to BSJ that the Celtics have reached out recently to begin discussions.
