  • The Action Network ranked all 32 starting quarterbacks based on their Week 4 fantasy football value.
  • Here's a deeper dive on two QBs you should start this weekend, including Patrick Mahomes.
  • We also break down two QBs you should stream and why you should fade another.

Which quarterbacks have the most favorable fantasy matchups? Who is the best streaming option? And who has a poor matchup?

Here’s a breakdown of five of the top fantasy football quarterbacks, as ranked by Sean Koerner, Chris Raybon and Matthew Freedman in their Week 4 fantasy football rankings.

The No. 1 QB

Patrick Mahomes, Kansas City Chiefs

Unsurprisingly, Mahomes is the unanimous No. 1 quarterback this week according to our rankers. He leads the league in passing touchdowns (13) and adjusted yards per attempt (12.4), and the Chiefs’ offense has scored on a league-best 53.1% of its drives (per Pro Football Reference).

Mahomes presently owns the highest median and ceiling projection in the FantasyLabs Player Models.

The Most Favorable Matchup

Philip Rivers, Los Angeles Chargers

Through the first three weeks, the 49ers have already surrendered the sixth-most passing yards (863), second-most passing touchdowns (8) and have lost Richard Sherman (calf) for a couple weeks.

Rivers has already tossed eight touchdown passes this season, and his 9.5 adjusted yards per attempt is the sixth-best mark in the league.
Koerner, Freedman and Raybon all have Rivers ranked within the top eight, and he boasts the second-highest ceiling projection in the FantasyLabs Player Models.

Matchup Downgrade

Ryan Fitzpatrick/Jameis Winston, Tampa Bay Buccaneers

The Buccaneers haven’t made a decision on their Week 4 starter as of writing. Either way, Tampa Bay is coming off some of its friendliest matchups to go on the road on a short week to take on a stingy Vic Fangio-coordinated defense that is allowing only 5.9 net yards per pass attempt and is second in the league in turnover rate.

The Buccaneers are implied for just 21.75 points, although the potential absence of Bears cornerback Prince Amukamara (hamstring) could provide a slight boost to Tampa Bay’s receiving corps.

The Best Streamers

Andy Dalton, Cincinnati Bengals

Ideally, A.J. Green (groin) will also suit up, but the Bengals haven’t commented on his status as of writing.

Regardless, Dalton has a solid matchup against a Falcons defense that continues to get less healthy. After losing Deion Jones (foot) and strong safety Keanu Neal (ACL) earlier, the Falcons also lost free safety Ricardo Allen (Achilles) following their Week 3 loss to the Saints.

Dalton has an average rank of 15.7 among our three rankers.

Case Keenum, Denver Broncos

The combination of the Chiefs’ high-scoring offense and dreadful defense is going to create a fantasy-friendly environment for opposing passing games.

The Chiefs have allowed opposing offenses to score on a league-high 48.4% of drives, and they’ve forced a turnover on only 3.2% of drives — tied for the second-worst mark in the league.

Keenum’s average rank of 15.3 just edges out Dalton for Week 4.
