Quarterbacks can win or lose you your NFL Fantasy matchup, as they often score the most points out of anyone on your team. The eternal question is relevant every week - who to start and who to sit?Every single week, fantasy owners spend hours deliberating on who to select, and that will be exactly the same in Week 4 this NFL season. Quarterbacks such as Lamar Jackson and Josh Allen are obvious starters this week, as they are in every matchup. However, others have question marks surrounding them as we enter Week 4 of the fantasy season.Week 4 NFL Fantasy Football Quarterbacks - Start 'Em#1 - Trevor LawrenceNFL - Jacksonville Jaguars v Los Angeles ChargersTrevor Lawrence was excellent in the Jacksonville Jaguars' 38-10 upset win over the Los Angeles Chargers. He passed for three touchdowns and no interceptions. The second-year signal-caller will come up against a solid 3-0 Philadelphia Eagles team in Week 4. But if you own Lawrence, you should start him. Jaguars HC Doug Pedersen formerly coached Philadelphia, so he should be familiar with some of their schemes and personnel. This is something that Lawrence can capitalize on.Jacksonville have also assembled a solid bunch of weapons for Lawrence, including Christian Kirk and James Robinson. The 18+ fantasy points he's put up in three of his last four outings makes him a solid starter in Week 4.NFL on CBS 🏈@NFLonCBSTrevor Lawrence is taking that HUGE leap forward 2021 2022W-L 3-14 2-1Pass TD 12 6INT 17 1QB Rating 71.9 103.1Comp pct 59.6% 69.4%2035204Trevor Lawrence is taking that HUGE leap forward 2021 2022W-L 3-14 2-1Pass TD 12 6INT 17 1QB Rating 71.9 103.1Comp pct 59.6% 69.4% https://t.co/wpaZvmj7cZ#2 - Russell WilsonNFL - San Francisco 49ers v Denver BroncosDespite struggling in his early days with the Denver Broncos, you should start Russell Wilson this week. Wilson comes up against division rivals the Las Vegas Raiders, who've allowed 22.63 fantasy points per game to QBs in 2022.That makes this a fairly easy matchup on paper for Wilson, who looked below-par against the San Francisco 49ers in Week 3. Despite being ranked as the 21st best fantasy QB so far in 2022, this matchup makes him a must-start.#3 - Joe BurrowNFL - Cincinnati Bengals v New York JetsJoe Burrow and the Cincinnati Bengals bounced back in Week 3. They claimed their first win of the season against the New York Jets and Burrow passed for 275 yards, three touchdowns and zero interceptions.Burrow comes up against Tua Tagovailoa and the Miami Dolphins on TNF in what could easily become a shootout. This makes both QBs must-starts. The Dolphins defense has allowed 25.95 FPPG to quarterbacks. You should start Burrow with confidence in Week 4.Sportskeeda Pro Football@SKProFootballJoe Burrow knows the Bengals have to be focused for a big challenge on Thursday Night...
