WASHINGTON (AP) — Wes Unseld, the workmanlike Hall of Fame center who led Washington to its only NBA championship and was chosen one of the 50 greatest players in league history, died Tuesday after a series of health issues, most recently pneumonia.

Unseld’s family announced his death via a statement released by the Washington Wizards, the franchise he was with throughout his entire 13-season playing career and also worked for as a coach and general manager.

A five-time All-Star and, along with Wilt Chamberlain, one of only two players to win NBA Rookie of the Year and MVP honors in the same season, Unseld instantly made the team then known as the Baltimore Bullets into a winner after he was taken with the No. 2 overall pick — behind future teammate Elvin Hayes — in the 1968 draft.

A decade later, Unseld was the MVP of the 1978 NBA Finals as the Bullets beat the Seattle SuperSonics in a seven-game series best known for Washington coach Dick Motta’s proclamation: “The opera ain’t over until the fat lady sings.”
