**Sacramento Kings and Milwaukee Bucks lead the market for the NBA's worst 2026-27 regular-season record due to their early 1-10 and 1-11 marks, respectively, alongside explicit rebuild signals.** The Kings have dealt with multiple frontcourt injuries, including Ben Simmons' preseason Achilles tear and absences for Maxime Raynaud and Keegan Murray, while leaning on rookie Darius Acuff Jr. amid defensive struggles and recent roster trimming via trades. Milwaukee's offseason blockbuster sending Giannis Antetokounmpo to the Heat in exchange for Tyler Herro and future assets has left the team in transition, yielding poor offensive and defensive outputs in a tough early schedule. These developments, paired with low projected win totals around 20-22, reflect trader consensus on their structural disadvantages compared to other bottom feeders like the Bulls, Jazz, or Clippers.
