As the 2025 NFL season enters Week 4, patterns are emerging that help fantasy football managers make sharper lineup decisions. Among the most valuable tools is the concept of the funnel defense — a team that naturally channels opponents toward passing or rushing due to its strengths and weaknesses. This week, several matchups stand out where funnel tendencies could significantly affect fantasy outcomes.
Pass Funnel Matchups
Cleveland Browns vs. Detroit Lions
The Lions are heavy home favorites and continue to operate as one of the NFL’s most consistent pass funnels. Detroit opponents have increased their pass rate by eight percent above expectation, forcing quarterbacks into high-volume situations. For Cleveland, that likely means Joe Flacco dropping back frequently, boosting the fantasy outlook for Jerry Jeudy, Cedric Tillman, and tight ends David Njoku and Harold Fannin. While the Browns’ ground game has been efficient, game script will almost certainly force them through the air.
San Francisco 49ers vs. Jacksonville Jaguars
Jacksonville’s defense has become a clear pass funnel, ranking near the top of the league in neutral pass rates allowed. Their strong run defense limits missed tackles and yards after contact, pushing opponents to attack through the air. Expect the 49ers to increase passing volume, benefiting Ricky Pearsall and Jauan Jennings if healthy, while Jake Tonges remains a deeper streaming option. Christian McCaffrey will continue to command targets as the offense adapts to Jacksonville’s strengths.
Run Funnel Matchups
Kansas City Chiefs vs. Baltimore Ravens
Baltimore’s defense has allowed an unusually high rate of explosive runs, shaping them into a run funnel opponent. Kansas City, despite its reputation for passing, has shown willingness to run in neutral situations. This week presents an opportunity for Isiah Pacheco and Kareem Hunt to exploit the Ravens’ vulnerability. Though Pacheco has yet to seize full control of the backfield, this matchup may provide one of his better chances to deliver strong fantasy production.
New York Jets vs. Miami Dolphins
The Jets’ commitment to a run-heavy identity aligns perfectly with Miami’s profile as a run funnel defense. Opponents have chosen to run at a high clip in neutral situations, which bodes well for Breece Hall. Hall dominates backfield carries and has been effective after contact, averaging 4.2 yards per rush. With favorable conditions, Hall could be in line for a breakout performance, making him one of the week’s stronger fantasy plays.
Identifying funnel defenses provides crucial insights for fantasy football decisions. In Week 4, pass-heavy scripts should benefit Cleveland and San Francisco receivers, while run-focused matchups could give Kansas City and New York backfields a significant boost. As the season progresses and sample sizes grow, these tendencies will become even clearer, offering managers a strategic edge in start-sit decisions.
