What happened: The 76ers added LeBron James in a two-year, $8 million deal that capped the Brown-George swap, pairing him with Tyrese Maxey and Joel Embiid in Philadelphia's starting five. The move immediately sparked debate over whether the new-look lineup is the best in the NBA.

Why it matters: The signing ends a Sixers Finals drought dating back to 2001. It also reshapes the Eastern Conference power rankings heading into training camp.

What to watch: Watch how the reshaped starting lineup performs once preseason games begin.
