Fantasy Football Start/Sit: Tyler Allgeier, Mason Taylor, Justin Jefferson

Week 14 is here, which means fantasy football managers everywhere are doing the same delicate dance: Pretending they’re calm while frantically refreshing injury reports and wondering why their most reliable starter suddenly turned into a decorative bench piece. With the fantasy playoffs looming, every lineup decision feels like it should come with its own dramatic score and slow-motion montage.

Fortunately, you don’t have to navigate the chaos alone. Our Featured Pros have once again sorted through the matchup quirks, usage trends, and late-season weirdness to highlight the Sleepers who can save your week… and the Duds who might quietly derail it. Let’s dive into who deserves a spot in your lineup and who’s better left on the fantasy equivalent of airplane mode.

Fantasy Football Week 14 Start/Sit Advice

Sleepers

Which player outside of the top 100 in the FantasyPros Flex rankings is a good sleeper start, and why do you think he has upside this week?

Tyler Allgeier (RB – ATL)

“Don’t let the ‘handcuff’ label fool you; Tyler Allgeier is a solid Flex play this week who co-exists with Bijan Robinson and is Atlanta’s preferred battering ram in the money zone, receiving 59% of the team’s carries inside the 5-yard line. Facing a Seattle defense that is tough to break down, Allgeier’s upside isn’t about yardage volume, but his high-risk high-reward role inside the 10-yard line, giving him a massive and reliable ceiling on what could be an otherwise ugly day on the ground.”
– Luke Renton (The Franchise Tag UK)

“While this is not the week to really go super off the reservation with who to start, Tyler Allgeier could make the cut as an intriguing play. Atlanta pounded the rock last week versus the Jets, with both Allgeier and Bijan Robinson gathering 31 carries between them. What makes Allgeier intriguing is his potential to gain goal-to-go touches, which he did last week, leading to a score. Consider Allgeier a touchdown-dependent deep league Flex play in Week 14.”

Mason Taylor (TE – NYJ)

“The Dolphins are one of the worst defenses in the NFL against the tight end position, and over the last couple of weeks, Tyrod Taylor has finally provided some consistency to the Jets’ passing game. With limited weapons in New York, Mason Taylor will have a lot of target upside this week versus Miami.”

Duds

Which player inside the top 40 in the FantasyPros Flex rankings is likely to disappoint fantasy managers this week?

Justin Jefferson (WR – MIN)

“Despite an expert consensus rankings (ECR) drop, Justin Jefferson is likely to disappoint because his elite talent is being hindered by the Vikings’ unstable quarterback situation. The drop-off from last year is less than ideal. With Sam Darnold in 2024, Jefferson was a WR1, averaging 90.2 receiving yards per game and posting 10 touchdowns for the season. However, with J.J. McCarthy under center, his production has been severely limited, a mere 53 receiving yards per game and zero top-eight weekly finishes this season, despite commanding a high target share. After the Week 13 horror show with Max Brosmer, McCarthy looks set to return, but this doesn’t fill me with any confidence at all. Expect another substandard display.”
