Joe Mazzulla has tried to avoid reflecting on the Celtics’ 2024 NBA championship since the team reconvened for training camp last month.

Opening night at TD Garden will include the raising of the Celtics’ 18th championship banner from the TD Garden rafters and the presentation of the team’s championship rings.
