Before you set your NFL DFS lineups on sites like FanDuel and DraftKings for Friday's action in Week 1 of the NFL preseason, see what Mike McClure has to say. McClure is a predictive data engineer and pro DFS player with almost $2 million in career winnings.

He uses a powerful prediction model that simulates every snap of NFL action in every game, taking factors such as matchups, statistical trends and injuries into account. This allows him to find the best DFS values and create optimal lineups that he shares only with members at SportsLine.

McClure absolutely rolled through the 2018 NFL season, cashing in the top 5 percent of tournaments on FanDuel and DraftKings multiple times. His optimal lineups cashed as high as the top 0.1 percent on FanDuel and as high as the top 1 percent on DraftKings. He's made some spot-on selections in the preseason thus far as well, picking Falcons quarterback Kurt Benkert (185 yards, TD) on both sites for the Hall of Fame Game. He also rostered the Ravens' defense on Thursday of Week 1. The result? They blanked the Jaguars and recorded four sacks and two INTs. Anyone who has followed McClure's picks has seen some HUGE returns. 

For Friday's action, where every player on FanDuel is $6,000 and every player on DraftKings is $5,500, one of McClure's top NFL DFS picks is Steelers wide receiver James Washington. Part of his optimal NFL DFS strategy includes rostering versatile Saints quarterback Taysom Hill, who should pile up production as a runner and passer as he gets extended reps against the Vikings. 

McClure is also targeting an overlooked player set to go off for MASSIVE numbers on Friday because of a dream matchup. This pick could be the difference between winning your tournaments or going home with nothing.
