Gibbs has started off the 2019 season on fire. His optimal has cashed on DraftKings in four of five weeks so far, including top-10 percent finishes in three of those weeks. In Week 1, Gibbs' optimal lineup absolutely crushed cash games. Led by 39.4 points from Austin Ekeler, the optimal finished with 188.32 DK points. Gibbs followed that up with a monster Week 2. Lamar Jackson led the way with 33.9 DK points, and the optimal finished in the top 10 percent in double ups again. In Week 4, Gibbs locked in a combined 77.7 DK points from his RB trio of Ekeler, Kerryon Johnson, and Wayne Gallman, which helped him to another top-10 percent finish. Now he's turned his attention to Week 6 of the NFL season.

For Week 6, Gibbs is high on Jaguars wide receiver D.J. Chark at $6,500 on FanDuel and $5,500 on DraftKings. Part of his optimal Week 6 NFL DFS strategy involves rostering Cardinals quarterback Kyler Murray ($7,700 on FanDuel, $6,500 on DraftKings), who gets a dream matchup against the Falcons, a defense that has given up the second-most Fantasy points to opposing defenses. 

Gibbs is also banking on a player who could score 30, even 40 points on FanDuel and DraftKings. This player could be the key to NFL DFS cashes, so you ABSOLUTELY need to his breakdown and optimal lineups before setting your own.
