The Boston Celtics have had no issue with chemistry.
I cannot stress this enough. The media have not reported any major chemistry issues with this team. This article is not meant to be a report of chemistry issues. From all accounts, the chemistry last year was fantastic. Kyrie Irving spoke in November about how he was building great relationships after every single game and practice. Terry Rozier spoke in May about how everyone was playing together on both sides of the ball. The Celtics had excellent chemistry this past year, an impressive feat considering all the new faces in the locker room.
