NFL Week 4 fantasy football start ’em, sit ’em

• Start Justin Fields: The Chicago Bears‘ 2023 season hasn’t gone according to plan, but a game against the Denver Broncos can help put Fields back on the right path.

• Sit Breece Hall: Hall’s playing time is trending up, but that doesn’t mean he will produce this week against the Kansas City Chiefs.

• Start Adam Thielen: While there are plenty of revenge games this week, trust Thielen for more reasons outside of the fact he’s playing the Minnesota Vikings.

Deciding who to start or sit in fantasy football can be as easy as looking at the PFF rankings and going with the higher-ranked player. This start ’em, sit ’em column digs a step deeper, looking into why someone you might typically start might not have a good week, or why someone overlooked might have a good week. In many cases, it’s the usual starters who should star, but we want to explore the borderline players, too.

QUARTERBACKS

START

Tua Tagovailoa, Miami Dolphins

• Tagovailoa is off to an excellent start this season. His 92.2 PFF grade is the best among quarterbacks.
• His 23.3 fantasy points per game ranks third among quarterbacks, and he ranked among the top three fantasy quarterbacks in two of the first three weeks.
• The only thing holding Tagovailoa back is he hasn’t been throwing as much as other quarterbacks. The Dolphins have built early leads and then haven't needed Tagovailoa to continue throwing.
• That should change this week, as the undefeated Dolphins are underdogs to the Buffalo Bills.
• The Bills have a great secondary but not a strong pass rush.
• Tagovailoa is averaging 10.6 yards per attempt with an 82.5% adjusted completion percentage without pressure. He has thrown a touchdown on 10% of his attempts.
• Even if Buffalo tries to generate pressure with a blitz, Tagovailoa has earned 91.0-plus PFF passing grades both with and without blitzes this season.

Justin Fields, Chicago Bears

• Fields hasn’t exactly lived up to fantasy managers' expectations so far, averaging just 14.6 fantasy points per game.
• He was drafted to be a top-six fantasy quarterback, and his opponent this week is a prime opportunity for him to turn his season around.
• The Bears have the sixth-best matchup for quarterbacks this week, according to PFF's strength of schedule tool.
• They play the Denver Broncos, who have allowed the second-most fantasy points to quarterbacks this season.
• Denver has the fifth-highest rate of using man defense so far this season.
• Fields has a 7.1% big-time throw percentage against man coverage and a 3.1% rate against zone coverage over the past two seasons.
• He also has a higher rate of scrambling against man defenses compared to zone, which should help his fantasy production.
