Celtics seeking 19th title, but challengers loom
Jayson Tatum was already a proven winner before last season. In Tatum's first six seasons, no NBA player won more games with one team than he did. Tatum played in 334 wins with the Boston Celtics over that span, including playoffs. He was a five-time All-Star, a legitimate MVP candidate, a four-time All-NBA pick, even an Olympic gold medalist.
