By Frank Pingue CLEVELAND - The Cleveland Cavaliers took another step in their historic comeback attempt with a 115-101 win over the Golden State Warriors on Thursday to force a once-unthinkable decisive seventh game to the NBA Finals. The LeBron James-led Cavaliers, one victory away from becoming the first team to win an NBA championship after falling behind 3-1 in the Finals, will now head to Oakland for Sunday's deciding game riding a wave of momentum. Cleveland used an explosive first half in which they led by as many as 22 points to set the tone and never allowed the usually sharp-shooting Warriors to settle into a rhythm or get any closer than seven points the rest of the way.
