The fourth week of the 2018 NFL preseason is upon us. Rather than being spread out over multiple days, the final preseason week features all 32 teams playing on the same night. The action gets underway on Thursday at 7 p.m. ET with a slate that includes Patriots-Giants, Rams-Saints, Cowboys-Texans, Chiefs-Packers, and Chargers-49ers in an all-California battle. The daily Fantasy sports sites FanDuel and DraftKings are offering plenty of tournaments and cash games as well, so before you lock in your NFL DFS picks for Thursday, you need to see what SportsLine's Mike McClure has to say.

McClure uses a powerful prediction model that simulates every snap of every game 10,000 times, taking factors like matchups, statistical trends and injuries into account. This allows him to find the best values and create optimal lineups that he shares only over at SportsLine. They're a must-see for any NFL DFS player. 

McClure has had some spot-on preseason NFL DFS picks already. In Week 3, he was all over Rams running back John Kelly. The result: Kelly exploded for 64 yards on the ground and two touchdowns -- returning 18.4 points on FanDuel. 

For the main NFL DFS slate on Thursday, every player on FanDuel costs $6,000 and every player on DraftKings is $5,500. 

One thing we can tell you: McClure is banking on Bears quarterback Tyler Bray. 

Chicago coach Matt Nagy announced that Bray is going to play the entire game for Chicago as he looks to solidify the third-string job. He has completed 60.3 percent of his passes in the preseason for 472 yards and a touchdown thus far. He's a top NFL DFS pick you should be all over on Thursday because it's rare to see players go the distance in a preseason game. 

Another preseason NFL DFS pick McClure loves: Broncos running back Royce Freeman. 

The rookie out of Oregon is making a strong push for the starting job in Denver thanks to a huge preseason. He has led all Denver rushers with 15 carries for 84 yards (5.6 yards per carry) and has scored once in each preseason game thus far. The Broncos are expected to give him more carries on Thursday as they make the final call for the starting role, so be sure Freeman is in your lineup.

McClure is also targeting a running back capable of putting up big numbers on Thursday. He's projected to see extended time, so this pick could be the difference between winning your tournaments and cash games or going home with nothing.
