The 2018-19 NBA season rolls on Sunday, Feb. 3 with three games on the NBA DFS main slate beginning at 1 p.m. ET. Before locking in your NBA DFS lineups for any tournaments, cash games, or 50-50s on FanDuel or DraftKings, check out the optimal lineups from SportsLine's proven computer model. 

This powerful prediction model simulates every minute of every game 10,000 times, taking factors like matchups, statistical trends and injuries into account. This allows it to find the best NBA DFS values and create optimal lineups for FanDuel and DraftKings. They're a must-see for any NBA DFS player.

On Saturday, the model recommended 76ers guard Jimmy Butler in its optimal lineup on DraftKings. The result? Butler had one of his best games in Philadelphia, going off for 29 points and seven assists -- returning 50 points on DraftKings and almost 7x value. Anybody who had him on their roster was well on the way to cashing. 

For Sunday's slate, the model is recommending Russell Westbrook at $11,700 on FanDuel and $11,000 on DraftKings. A value pick the model loves: Danny Green ($4,600 on FanDuel, $4,200 on DraftKings), who should see plenty of minutes for the Raptors on Sunday. 

The model is also targeting a sleeper who has a dream matchup on Sunday. The stars are aligning for him to return 40, even 50 points on both sites, and he comes at a rock-bottom price. This pick could be the difference between winning your tournaments and cash games or going home with nothing.
