By Frank Pingue CLEVELAND - LeBron James is closing in on what would be the greatest feat of an already storied NBA career after putting his Cleveland Cavaliers in position to end a half century of heartbreak for the city. Five years after he was vilified in Cleveland for leaving the team for Miami in pursuit of championships, James has the Cavaliers two wins away from an upset victory over the top-seeded Golden State Warriors in the best-of-seven NBA Finals. "It was a bitter moment when I left the first time, but it's a sweet moment here now that I'm back," James told reporters on Wednesday a day before the Cavaliers host a pivotal Game Four.
