NBA season opens with Sixers upsetting champion Knicks

Philadelphia beat the defending champion Knicks 106-100 at Madison Square Garden; Tyrese Maxey scored 28, and LeBron James occasionally played center and defended Karl-Anthony Towns. Oklahoma City beat San Antonio 116-104, and Detroit stunned Boston with a 23-0 fourth-quarter run after trailing by 22. These opening-night results and tactical observations are an early snapshot, not settled trends.
