JB is likely to leave Boston this off season so the Celtics would like a sign and trade. Because the Celtics would likely lose him anyways, they would lower his value. The hawks are one of the top contenders to get him as they want to help Trae. JB is also from Atlanta. The Celtics would also receive their first true points guard since Kyrie, giving the best defensive backcourt in the league. They would also receive a great defensive center, similar to Robert Williams
