Task: Question Understanding
Input (English): Passage: Prior to the start of the 2017-18 NBA season season, the Cavaliers overhauled their roster by moving Kyrie Irving to the 2017-18 Boston Celtics season, who requested a trade in part because he no longer wanted to play with James. After a slow start to the year, Cleveland rebounded by winning 18 of 19 games in December. Their turnaround began with a victory over the 2017-18 Washington Wizards season where James scored 57 points, which represented the second-highest point total of his career and tied a franchise record. In January, the Cavaliers had a losing record, and James was criticized for his lackluster effort. Following another round of trades in February, Cleveland returned to form and James reached a number of historical milestones; for example, on March 30, he set an NBA record with 867 straight games scoring in double-digits. James eventually finished the season with averages of 27.5 points, 8.6 rebounds, and a career-high 9.2 assists and 4.2 turnovers per game. In the 2018 NBA Playoffs, he guided the Cavaliers to another Finals rematch with the 2017-18 Golden State Warriors season. Along the way, he had some of the most memorable moments of his career, including a game-winning shot against the 2017-18 Indiana Pacers season and another against the 2017-18 Toronto Raptors season. In the first game of the 2018 NBA Finals, James scored a playoff career-high 51 points, but Cleveland was defeated in overtime. Following the defeat, James injured his hand after punching a wall in the locker room, which hindered his effectiveness for the remainder of the series. The Cavaliers lost the series in four games, with James averaging 34 points, 8.5 rebounds, and 10 assists per game for the Finals.
Question: How many more assists than rebounds did James have on average in the 2017-18 season?
