Before you set your Fantasy Football Week 13 lineups or lock in your DFS picks for this weekend's games, you NEED to see what SportsLine's highly-rated expert Jacob Gibbs has to say. Gibbs' Fantasy football draft rankings were the eighth-most accurate in the nation across the 2018-20 seasons, per FantasyPros, and he is back with Week 12 Fantasy Football rankings for SportsLine users.

In 2018, Gibbs predicted Patrick Mahomes' Fantasy explosion. In 2019, he projected big-time breakouts for Lamar Jackson and Chris Godwin, while also identifying Darren Waller as the top late-round tight end pick. Last season, Gibbs was one of the few analysts who ranked Davante Adams as Fantasy's WR1 entering the season, and he was all over the breakout seasons for Calvin Ridley and Antonio Gibson. Anyone who has followed Gibbs advice over the past three seasons has been well on their way to a league title.

Now, Gibbs has projected every Fantasy-relevant player's stats for Week 13. One player Gibbs is especially high on: Detroit RB Jamaal Williams. Williams has an expert consensus ranking of RB20, according to FantasyPros, but Gibbs has him ranked in the top 12 for Week 13.

Gibbs also is calling for a QB you aren't even thinking about to finish in the top 10 at his position! This player could be the difference between winning BIG or going home with nothing.

So who are the best players to target at each position in Week 13? And which RB that you aren't thinking about is set to put up a monster point total? ...
