Cleveland sports fans have suffered so much heartache in 51 years without a champion that the most painful moments have their own names: The Shot, The Drive and The Fumble. Now the Cleveland Cavaliers are on the verge of adding another chapter to that legacy of frustration as they face a must-win situation in Tuesday's sixth game of the NBA Finals. The Golden State Warriors seized a 3-2 lead in the best-of-seven title series with a 104-91 home victory Sunday, meaning the Cavaliers must win Tuesday at home to force a seventh game Thursday in California.
