Building Preseason NFL DFS lineups this Thursday? See what SportsLine's DFS Guru Jacob Gibbs has to say first. Gibbs is a data-driven Daily Fantasy Sports specialist who's never had a losing season.

Previously an analyst at numberFire, Jacob got his start in DFS six years ago, turning a $25 deposit into nearly $3,000 his first season. Gibbs crushed NFL season last year, cashing around 57 percent of the time in cash games and nearly 40 percent of the time in tournaments. Those numbers jumped way up during the preseason, where Gibbs posted an eye-popping 44% ROI in tournament play. He also develops proprietary rankings and projections, which help him find the best DFS values and create profitable lineups. Be sure to check his lineups and player pool out daily before setting your own lineups.

Gibbs has spent hours scouring training camp news over the past week and has you prepared with a tiered positional breakdown for cash games and tournaments.

One thing we can tell you, is that he is enamored with New England's third-round running back Damien Harris. "None of Sony Michel, Rex Burkhead, or James White will play tonight, and the Pats know what they have in veterans Brandon Bolden and James Develin. Expect a big workload for Harris, who is among the most talented backs projected for significant volume on Thursday," Gibbs said.

Gibbs also has his eye on Chicago Bears wide receiver Javon Wims, who led the entire NFL in receiving yards last preseason. Wims has the size and athleticism to post big numbers against second- and third-string defenders, and Gibbs believes he is a must-play on a weak wide receiver slate.
