Oklahoma City Thunder lead trader consensus at 36.5% implied probability to repeat as NBA champions, bolstered by their league-best 58-16 record as of March 29, securing the No. 1 Western Conference seed and rest advantages ahead of the playoffs, with Shai Gilgeous-Alexander strengthening his MVP case by surpassing Wilt Chamberlain's scoring consistency record last week. San Antonio Spurs follow at 17.3%, riding Victor Wembanyama's dominant two-way play and a 56-18 mark just two games back, positioning them for a potential deep postseason run. Boston Celtics sit third at 11.8% despite a strong 50-24 East record, but recent injuries to Jaylen Brown (Achilles), Derrick White (knee), and trade acquisition Nikola Vucevic (finger surgery, out 3-4 weeks) have eroded their title defense momentum post-February trade deadline. Denver Nuggets' 8.5% reflects Nikola Jokić's triple-double averages amid a 47-28 standing, while Eastern leaders like Cleveland Cavaliers and Detroit Pistons hover around 4-5% on solid form but tougher paths.
