Tatum ruptured his right Achilles in May during the 2025 playoffs, and rather than sitting out all of 2025-26 as expected, he returned in early March. Shockingly, he hardly faced any limitations, averaging 33.6 minutes per game across 22 appearances, postseason included. While he wasn't as efficient from the field as he usually is, Tatum was still very productive, averaging 22.2 points, 10.2 rebounds, 5.7 assists and 1.3 steals per game. However, he briefly left Game 6 of the opening-round playoff series against Philadelphia after appearing to tweak his knee, and while he downplayed the issue afterward, Tatum ended up missing Game 7, which Boston lost 109-100. The extent of the knee injury wasn't disclosed, but it's safe to assume the six-time All-Star was battling serious pain if the medical staff opted to shut him down. Presumably, Tatum will be 100 percent for training camp in 2026-27, though the team could proceed with caution throughout the year. Tatum's recent injury history isn't even the biggest storyline in Boston, as Jaylen Brown's relationship with the Celtics soured so badly that they had to flip him to an Eastern Conference rival, the Philadelphia 76ers. Newcomer Paul George should replace most of the missing production, but Brown averaged 19.3 shots per game over the past six seasons, opening up more opportunities for Tatum, Derrick White and Payton Pritchard as well. Tatum is still only 28 years old and already proven to be one of the elite players in the league, giving him a top-10 fantasy upside when fully healthy. He's not as sure of a lock as he was a few years ago, but Tatum's track record of consistently producing superstar production is tough to match.
