Jaylen Brown is entering his 10th NBA season, and this year could be the most significant of his career. All-Star forward Jayson Tatum is likely to be sidelined for most, if not the entirety, of the season due to an Achilles tear. In his absence, Brown will step up as the team’s No. The Celtics’ success this season relies on how far Brown can take them, and NBC Sports Boston’s Michael Hurley hopes to see Brown selected for an All-NBA Team. “I think he has to make an All-NBA Team,” Hurley wrote Monday.
