James Harden, Houston Rockets
The top fantasy line of the 2017-18 season came on January 30th, when James Harden dropped the first 60-point triple-double in NBA history, scoring 60 points on 19-for-30 shooting from the field, 5-for-14 from three-point range, and 17-for-18 from the free throw line, with 10 rebounds, 11 assists, 4 steals, and a block to go along with it.
That was good for 98.5 FanDuel points, which represents the highest total achieved by any player in a single game this season and the second-highest in FanDuel's history (2009 to present). It was also the best game by BasketballMonster.com's "value" rating at 4.14 (Joel Embiid had the next closest mark this season with 3.52 for his November 15th performance).
We got plenty of big fantasy lines from various players this season, but this one was number one with a bullet.
Honorable Mention: Anthony Davis (New Orleans Pelicans) on February 14th, 23rd, and 26th, 2018, DeMarcus Cousins (New Orleans Pelicans) on January 22nd, 2018, Joel Embiid (Philadelphia 76ers) on November 15th, 2017.
