Boston Celtics hold a slim trader edge at 32% implied probability for Eastern Conference champion, buoyed by their 3-2 first-round series lead over Philadelphia 76ers, where Joel Embiid remains probable but hampered by ongoing injury concerns, allowing Jayson Tatum to shine post-Achilles recovery. New York Knicks trail closely at 27% after forging a 3-2 advantage versus Atlanta Hawks, leveraging Josh Hart's questionable status but gritty depth in tight games. Cleveland Cavaliers sit at 23.5% following recent wins to seize control against Toronto Raptors, capitalizing on superior regular-season form over Detroit Pistons, whose 6.5% odds reflect trailing Orlando Magic 2-3 despite the top seed—though Magic's Franz Wagner calf injury absence for Game 6 tilts momentum back. With all top series extended into late first round amid fluid injury reports and upset risks, the race stays fiercely competitive.
