After three weeks of action, we fantasy football players feel like we know everything. Sort of.
In this week's sleepers lineup report, we're rolling with some big Week 3 performers once again, while entrusting some underperformers with the potential for a big game in a favorable matchup.
Keep scrolling for The Sporting News' staff picks for Week 4 fantasy sleepers.
Best Week 4 Fantasy Sleepers
QB sleeper picks this week
Jordan Love, Packers at Cowboys
The Cowboys are the classic bad pass defense with little pressure and bad coverage and they also give up a ton of big plays downfield. Love will use them to get well to wake up the more aggressive version of the Packers' offense with Matthew Golden and others. - Vinnie Iyer
Carson Wentz, Vikings vs. Steelers
Wentz's Minnesota homecoming went swimmingly, with the Vikings dismantling the Bengals 48-10. Now the veteran gets to face the Steelers on a neutral field in Dublin, and the results should be even more plentiful. Pittsburgh's defense ain't what it used to be — it has surrendered the fourth-most fantasy points to the QB position through three weeks. - Sloan Piva
Geno Smith, Raiders vs. Bears
Geno Smith just had an excellent fantasy performance in Week 3; now, in Week 4, he gets to face the Bears defense, which has allowed the 4th most fantasy points per game to the QB position thus far. - Griffin Missant
TOP FANTASY PICKUPS: Week 4 waiver wire
RB sleeper picks this week
Omarion Hampton, Chargers at Giants
This is more of a confidence booster. Some Hampton managers might be skeptical, but the volume alone with Najee Harris down makes Hampton a must-start against the Giants. - Griffin Missant
Kareem Hunt, Chiefs vs. Ravens
The Ravens are having trouble slowing down running backs in the red zone and the Chiefs should have more rushing success than expected at home with Hunt getting the ball and cashing in for paydirt at least one more time with Isiah Pacheco fading as a factor. - Vinnie Iyer
Ollie Gordon, Dolphins vs. Jets
Gordon has the "it" factor or the juice or whatever you want to call it. He turned nine carries into 38 yards and a touchdown in Buffalo last Thursday, and now he's got plenty of time to rest his rookie body ahead of this Monday Night Football clash with the Jets. New York sits among the top 10 most generous defenses to opposing RBs in fantasy, so both De'Von Achane and Gordon should eat.- Sloan Piva
LAST WEEK’S RECAP: What happened in fantasy Week 3 | Week 3 Injuries
WR sleeper picks this week
Quentin Johnston, Chargers at Giants
Screw "sleeper" — Quentin Johnston has moved into "must-start" territory. With approximate PPR totals of 25, 16 and 15 through his first three games, he's a legitimate WR2 within the Chargers' elite passing attack. And, while the Giants have a solid pass-rush, their secondary still gives up plenty of chunk-yard plays downfield (Tyquan Thornton proved that on Sunday night). - Sloan Piva
Matthew Golden, Packers at Cowboys
The Dallas Cowboys have allowed 47.9 fantasy points per game to the WR position (in PPR). Every Packers WR is a must-start, but I like Golden to have his breakout against Dallas. - Griffin Missant
Tre Tucker, Raiders vs. Bears
In three games with Geno Smith, he has caught 13 of 20 targets for 211 yards and 4 TDs (tied for the league lead). He has stepped to help Jakobi Meyers with the young wideouts still needing time to get on track and that big-play role will continue vs. Chicago's secondary at home. - Vinnie Iyer

TE sleeper picks this week
Hunter Henry, Patriots vs. Panthers
Henry scored twice with Drake Maye against the Steelers and as expected, he's emerging as the most reliable go-to guy for the second-year QB. He can put together another big game vs. the Panthers' defense, which still struggles to cover the position well. - Vinnie Iyer
Brenton Strange, Jaguars at 49ers
Strange quietly hauled in 6-of-7 targets for 61 yards on Sunday, and now he faces a 49ers defense that has allowed Juwan Johnson and Trey McBride to each surpass 15 PPR points over the past two weeks. Only 25-percent rostered at the start of the week, Strange is a true sleeper who could help countless fantasy teams in need of TE upgrades. - Sloan Piva
Mason Taylor, Jets at Dolphins
Mason Taylor has yet to have his breakout performance, even though the talent is there. In Week 3, he was targeted the most this season with Tyrod Taylor as the QB. In Week 4, the Jets take on the Dolphons, who have allowed 17.2 fantasy points per game to the TE position. - Griffin Missant

Team Defense sleeper picks this week
Houston Texans vs. Titans
Houston's defense is far from good, but remember, the matchups matter more. They get to take on Cam Ward, who has struggled to score points and just threw a pick-six in Week 3. - Griffin Missant
Detroit Lions vs. Browns
The Jaguars have their share of pass rushers, led by Josh Hines-Allen and Travon Walker, and the Texans' offensive line is really struggling in front of C.J. Stroud. Sacks will be had with a chance for their secondary to make a big game-changing play to further bury the visiting reigning AFC South champions. - Vinnie Iyer
Los Angeles Rams vs. Colts
Lots of fantasy managers cut the Rams loose in Week 3 because they were facing the Eagles. Well, that's a pity, because this has been one of the better defensive units in football. With 12 sacks and four takeaways through three weeks — not to mention an average of just 18.3 offensive points allowed — Los Angeles seems like a prime candidate to stop Indy's momentum dead in its tracks. - Sloan Piva
