The NBA is back.
The Celtics will kick off the regular season on Wednesday night against the Philadelphia 76ers, a matchup of teams that have faced each other 21 times in NBA postseasons — the most in NBA history. Most recently, Boston defeated Philadelphia in the 2018 Eastern Conference semifinals.
This season, the rivalry includes some crossed allegiances. Former Celtics big-man Al Horford, who signed a four-year $97 million-deal with the Sixers in free agency, will face the team he played on for the past three seasons. Horford was asked how he feels about the upcoming matchup.
