He can help you put together the optimal NFL DFS picks on sites like DraftKings and FanDuel. He'll also help you decide whether you can trust potential fill-in starters like Seahawks quarterback Drew Lock and Packers running back Patrick Taylor.

Gibbs uses a data-driven approach that has helped him consistently provide accurate rankings at every position. He has proven to be one of the nation's most accurate Fantasy rankers in recent years, posting the eighth-most accurate results over the past few seasons, according to Fantasy Pros.

One player Gibbs is especially high on: Buccaneers RB Rachaad White ($7,400 on DraftKings, $7,700 on FanDuel). Gibbs is also rostering Bears receiver D.J. Moore ($6,900 on DraftKings, $8,200 on FanDuel). Moore has benefited significantly from Justin Fields' return, and the Bears have a Week 16 implied point total that is significantly higher than usual in a favorable matchup against the Cardinals.

Gibbs also is calling for an underpriced running back you aren't even thinking about to score 15 to 25 points on DraftKings and FanDuel! This player could be the difference between winning BIG or going home with nothing.
