Sunday’s NBA tip-offs all come early and NBA DFS players who are looking to get in on the action on FanDuel and DraftKings won’t have a lot of time to get their NBA DFS lineups locked in before the Grizzlies and Knicks start at 1 p.m. ET. Of course, the marquee matchup of the day is the Boston Celtics against the Oklahoma City Thunder at 2 p.m. ET as Russell Westbrook and Kyrie Irving are the two highest-priced options available for Sunday’s action. Then the Clippers and Raptors will wrap up the day’s NBA DFS tournaments and cash games with a 3 p.m. ET tip. But before locking in your Sunday lineups be sure to check out the NBA DFS picks and lineups from the proven computer model at SportsLine.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 that are only over at SportsLine. 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. Westbrook is the most expensive player on DraftKings, but only by $100. He’s the second most on FanDuel, behind teammate Paul George. The model has found value on him for a matchup against the Celtics because he’s been absolutely stuffing the stat sheets recently. He’s still able to go off for 30 points on any given night, but he’s been a triple-double machine, entering Sunday with five in a row.Part of the NBA DFS strategy the model is recommending is targeting Raptors guard Danny Green ($4,600 on FanDuel and $4,200 on DraftKings). Green should be ready for starter’s minutes again after playing just 13 minutes because of an illness on Thursday night. He previously had played at least 20 minutes in the nine previous games and had averaged 27.2 points on FanDuel for an average return of over 6x.The shooting guard is helping the Raptors space the floor by shooting 42.1 percent from beyond the arc (his best percentage in the last six seasons) and he should get looks on Sunday against the Clippers. They’re middle of the road when it comes to defending shooting guards, allowing the 16th-most points to the position in the NBA so far this season.The model is also targeting a sleeper capable of putting up big numbers 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.So who is SportsLine’s proven computer model putting in its optimal NBA DFS lineup for Sunday?
