The word "sleeper" gets thrown around a lot in the world of fantasy football, to the point where an actual definition may vary from person to person. In general, sleepers are NFL players who may be flying relatively under the radar in a particular field. That could be an under-rostered player in season-long leagues, a player with an exciting matchup in a given week, or even a potential star just ahead of their true breakout.

In any case, we all need to find a sleeper from time to time. Whether you're a fantasy football hipster looking to roster an exciting new player before your league-mates hear about him, a daily fantasy manager looking for a lower-salary player to fill out a lineup loaded with studs, or even just a manager in a pinch due to byes or injuries, we have you covered. We'll be bringing you six fantasy sleepers each and every week throughout the season.

Fantasy Football Week 7 Sleepers

Josh Dobbs, QB, Arizona Cardinals

FanDuel Salary: $6,600

Arizona Cardinals interim quarterback Joshua Dobbs has been shockingly feisty so far in 2023. He's played some brutal NFL defenses, including numberFire's second- and fifth-ranked defenses in the Dallas Cowboys and San Francisco 49ers, but he has still managed to eke out a spot as fantasy's QB18 on the year.

Simply put, Dobbs has been a gamer. Incumbent starter Kyler Murray's impending return is looming now that the team opened his 21-day practice window, but the former first-overall pick is still expected to need a couple of weeks to practice before he starts under center.

We didn't know much about Dobbs entering the season -- his 196 pass attempts this year are already more than double his previous career totals -- but he's shown off a set of wheels we didn't know we could bank on for fantasy football. He's put up 189 rushing yards and a touchdown on 34 rush attempts this season, which gives him a surprisingly high floor even when Arizona's passing game isn't on point.

If we exclude his poor Week 1 showing -- which would be fair, considering he had only been with the team for a couple of weeks at that point -- Dobbs has actually been a good fantasy starter more often than not. And this week, he'll get to take on the Seattle Seahawks, whose defense is allowing opposing passers to throw for the fifth-most yards per game (257.6).

With his softest matchup in weeks on the docket, Dobbs could be queued up for a nice fantasy outing this weekend.

Wan'Dale Robinson, WR, New York Giants

FanDuel Salary: $5,600

The New York Giants need someone to step up for them on offense, and it's starting to look like Wan'Dale Robinson could be that guy.

The team has been slowly ramping their 2022 second-round pick up to full speed as he finishes off his recovery from last year's season-ending knee injury, and it looks like he's ready to become a consistent contributor.

Robinson has drawn at least five targets in each of his four games so far this season, with six, six, and eight over his last three contests, respectively. His involvement looks like it's trending upwards as the season goes on, and with none of the team's other receivers stepping up, he could continue garnering an increasingly large share of the offense. He's pacing the Giants' wideouts in yards per route run (1.45) and trails only Darius Slayton (236) in total receiving yards (141) despite sitting out the first two games of the season.

His current usage makes him viable in PPR-based formats on volume alone, though we still need to see him garner more looks down the field before he can become an every-week starter in non-PPR formats. His 3.2 average depth of target (aDOT) ranks fourth-closest to the line of scrimmage among receivers and tight ends.

Fortunately, his Week 7 matchup against the Washington Commanders -- whose defense has allowed the third-most fantasy points per game to opposing receivers -- should help him produce efficiently regardless of his low-aDOT targets.

With his targets per game trending in the right direction and without another consistent receiver on the Giants' offense, we could see Robinson hit double-digit targets against Washington.

Kadarius Toney, WR, Kansas City Chiefs

FanDuel Salary: $5,500

Sleeper or not, Kadarius Toney is not a fantasy player for the faint of heart.

We're all just as aware of the former first-round pick's unique skillset and potential to score fantasy points as we are of his ability to completely vanish on any given day. He's been a ghost in the box scores for most of the year and is now available on waiver wires in more leagues than not.

While Toney has been one of the biggest boom-or-bust plays in fantasy since entering the league, his recent usage rates with the Kansas City Chiefs have been a little exciting.

After missing a game and a half with a toe injury earlier this year, his snap totals have climbed from 17 to 25 to 30 over the past three games. He's seen six targets in the Chiefs' two most recent games and trails only superstar Tyreek Hill among qualified wide receivers in targets per route run (0.33) on the season. In other words, the Chiefs love to target Toney when he is on the field, and Toney's playing time looks like it is trending up.

The Chiefs have a pretty nice-looking matchup on paper for their receivers this week, as well. No team is giving up more fantasy points to opposing wideouts than the Los Angeles Chargers. That means that even if the Chiefs continue to run their receiver room by committee, there's a pretty good chance that whoever does draw targets will be able to convert them into fantasy points pretty efficiently.

If Toney keeps ramping up his playing time and those target rates stay stable, he could be in line for a really nice fantasy outing.

Keaontay Ingram, RB, Arizona Cardinals

FanDuel Salary: $5,700

The Cardinals really felt the loss of James Conner in Week 6 but still managed to churn out 130 rushing yards on the ground against the Los Angeles Rams. Their running game, whose 90.3 PFF grade ranks second, has been sneaky good all year. What they're doing is working, and it sets their running backs up for good fantasy football roles.

The team used a committee to help fill Conner's shoes in Week 6, but second-year back Keaontay Ingram looks poised to assume the lead role going forward.

Despite only just returning to the team from a neck injury that sidelined him for multiple weeks, Ingram still led the team's backfield in carries (10) and targets (2) last Sunday while both journeyman Damien Williams and potential rival Emari Demercado trailed him in opportunities. The team hasn't outright specified that Ingram will be their lead back going forward, but when connecting the dots here, it looks like once he's fully recovered from his neck injury, they'll look to lean on him until Conner's return.

Ingram is one of the few backs widely available on waiver wires who could dominate his team's running back opportunities over the next few weeks. If he does absorb his teammates' workloads against the Seahawks on Sunday, you'll wish you had picked him up now instead of having to fight for him on waivers ahead of Week 8.

Craig Reynolds, RB, Detroit Lions

FanDuel Salary: $5,600

Has any non-Christian McCaffrey-backfield been more fantasy-friendly than the Detroit Lions' backfield over the past two seasons?

A year removed from Jamaal Williams leading the league in touchdowns, former Chicago Bears back David Montgomery has already notched six rushing scores in five games as Detroit's top rusher. If the Lions have a goal-line back, you'll probably want him on your fantasy team.

Montgomery is currently dealing with a rib injury, which could open the door for another back to handle that role against the Baltimore Ravens this week. The team let first round pick Jahmyr Gibbs try his hand -- unsuccessfully -- at the role when Montgomery missed the team's Week 3 contest, and now that Gibbs himself is also managing an injury, the team could turn to Craig Reynolds as their primary back against Baltimore.

Reynolds isn't likely to be more than a one- or two-week contributor for your fantasy teams, but sometimes that's all you need. There's a good chance he'll operate as the Lions' goal line back this week, making him a fine starter in fantasy football.

Michael Mayer, TE, Las Vegas Raiders

FanDuel Salary: $4,900

It only took, like, six weeks, but the Las Vegas Raiders finally remembered that they drafted former Notre Dame Fighting Irish tight end Michael Mayer in the third round of this year's NFL Draft. And now that they've remembered him, you're going to want to make room for Mayer on your fantasy rosters.

Mayer was the engine of Notre Dame's passing offense in his three seasons with the team and is now living up to his billing as an elite pass-catching option at the position in the NFL. After popping up for 39 yards on 2 catches in Week 5, Mayer caught 5 of 6 targets for an impressive 75-yard day in Week 6. He's finally running more routes than teammate Austin Hooper and looks poised to make an impact for the Raiders' passing game.

Even if Jimmy Garoppolo sits the week out due to his new back injury, the Raiders should still be able to get some targets Mayer's way against the Bears' pitiful pass defense. Tight ends have caught 40 of 48 (83.3%) of their targets when facing the Bears, who have given up solid outings to each decent pass-catching tight end they've faced on the year.

It's incredibly difficult to find difference-makers for fantasy at the tight end position, but Mayer profiled like a potential fantasy stud in college. If he's available on waivers in your leagues, he should be a priority add for pretty much any team that didn't draft Travis Kelce, T.J. Hockenson, or Mark Andrews.
