The Boston Celtics will host the Philadelphia 76ers at TD Garden on Christmas Day, continuing a storied rivalry that dates back to Bill Russell and Wilt Chamberlain. This marks the ninth consecutive Christmas Day appearance for the Celtics, who are coming off a championship season. The 76ers have significantly revamped their roster, adding Paul George, Eric Gordon, and Reggie Jackson, and re-signing key players like Tyrese Maxey and Kelly Oubre Jr., making them a formidable opponent. Philadelphia's president of basketball operations, Darryl Morey, has expressed confidence in challenging the reigning champions for the title. The last Christmas Day matchup between these teams was in 2018, which Boston won 121-114 in overtime. This high-profile game is part of a broader NBA Christmas slate that includes other marquee matchups.
