LeBron James and the Cleveland Cavaliers will celebrate their city's first sports crown in 52 years on Tuesday, raising their championship banner as the 2016-17 NBA campaign opens. The Golden State Warriors, meanwhile, will welcome superstar forward Kevin Durant to the fold as they set out to avenge their loss to Cleveland in last June's NBA Finals after coming one game shy of back-to-back titles. The Cavaliers and Warriors open the season as favorites to play each other in the finals for the third campaign in a row, an unprecedented feat, even as 28 rivals try to fight their way into next June's title showdown.
