The NFL season is heading towards the quarter mark and it's likely desperation time for those fantasy owners who are yet to claim a win.

Thankfully there are several matchups in Week 4 that figure to be very high scoring and deliver huge fantasy performances.

Which players should you be looking at slotting into your lineup for the upcoming slate of games?

Stats Perform looks at four offensive players and a defense that can help propel you to glory this week.

Quarterback: Ryan Tannehill, Tennessee Titans @ New York Jets

Tannehill followed up a 300-yard performance in Week 2 against the Seattle Seahawks with a three-touchdown display in a win over the Indianapolis Colts.

The Jets' defense is the strength of their winless team but still ranks 17th in the NFL in yards per pass play allowed with 6.79.

Given the ineptitude of New York's offense, which has committed the second-most turnovers in the NFL (7) through three games, the Jets' defense is likely to eventually wear down and provide Tannehill with plentiful opportunities to enjoy another strong fantasy outing.

Running Back: Austin Ekeler, Los Angeles Chargers vs. Las Vegas Raiders

The Chargers have their own problems with run defense, allowing the highest rushing average in the league at 5.8 yards.

However, fourth on that list are the Raiders, who have given up 4.81 yards per carry through three games.

Ekeler's yards after contact per attempt average of 2.5 is sixth among running backs with at least 10 carries and he is again a focal point in the passing game having made 15 receptions over the last two games. 

In a game likely to be dominated by high-powered offenses, Ekeler figures to play a pivotal role and, taking the favourable matchup into account, is a must-start in points per reception fantasy leagues.

Wide Receiver: Tyler Lockett, Seattle Seahawks @ San Francisco 49ers

Lockett has never had a 100-yard game against the 49ers, but caught 12 of 14 targets for 90 yards and two touchdowns in the regular-season finale against San Francisco last year.

Registering a burn, which is when a receiver wins his matchup on a play where is targeted, on 68.4 per cent of his targets Lockett is second among wide receivers that have been thrown to at least 10 times with a burn yards per target average of 19.29.

Going up against a banged-up San Francisco secondary, Lockett's ability to create consistent separation could prove pivotal in a matchup where Seattle may have to get into a shootout to prevail given the porous nature of the Seahawks' defense.

Tight End: Dawson Knox, Buffalo Bills vs. Houston Texans

Still the most difficult position in fantasy football to judge, managers can often find themselves in a difficult spot if they do not own one of Travis Kelce, George Kittle and Darren Waller.

However, those lacking a dependable option at tight end may find Knox a worthwhile pickup for this week. He has a touchdown in each of his last two games, hauling in four of his five targets last week against the Washington Football Team, and gets an extremely enticing matchup in Week 4.

The Texans are allowing the fourth-most fantasy points per game to opposing tight ends and, with the Bills' offense beginning to fire on all cylinders, Knox could prove an extremely astute addition to fantasy lineups if he is still available on your waiver wire.

Defense: New Orleans Saints vs. New York Giants

The Saints' defense had a field day in Week 3, picking off rookie Mac Jones three times, including one interception returned for a touchdown, in a bounce-back win over the New England Patriots.

This week, New Orleans gets to play a game at the Superdome for the first time this season, and the impact of a raucous home crowd will surely only make things more difficult for the Giants' offense and quarterback Daniel Jones.

He has been pressured 53 times already this season, the Giants allowing the 11th-most in the NFL, while the Saints' defense has racked up 56 pressures, putting New Orleans seventh in the league.

While the Giants' signal-caller has only committed one giveaway in 2021, that is a recipe for a disastrous day for a quarterback known for his lack of ball security. Should this go to form, the Saints will make life miserable for a quarterback named Jones for the second successive week.
