For most, the 2025 fantasy football season is over for another year, after 17 weeks that have featured the good, the bad, and the bizarre. However, for the true sickos, Week 18 provides a wild alternative ending to a fantasy season, with several teams set to rest key players ahead of the playoffs.
If you’re looking to stream a week-winning defense this week, here are three of the best available options.

Streaming Defenses for Week 18: Minnesota Vikings (vs. GB)
The Minnesota Vikings are one of the best defenses in the NFL, and are coming off three top-four fantasy finishes in their last four weeks. That includes a DEF1 overall finish in Week 17, against an elite Detroit Lions offense.
This week, they face the Green Bay Packers, who, now assured of the seventh seed in the NFC, are almost certain to rest key starters after limping to three consecutive defeats. That would mean Jordan Love, Josh Jacobs, and potentially even Malik Willis, who has been suffering with a shoulder injury.
That would put third-string quarterback Clayton Tune up against one of the NFL’s premier pass defenses, and make the Vikings defense a must-start in fantasy.
Jacksonville Jaguars (vs. TEN)
The Tennessee Titans rank 30th in PFSN’s Offense Impact metric, but that hasn’t always translated into fantasy value for opposing defenses. However, the Jacksonville Jaguars boast the third-best defense in fantasy this season, and have finished outside the top-12 just twice in their last eight games.
The Jaguars’ defense is rostered in 51% of Yahoo leagues, a little over the threshold for this article, but they are performing so well that it would be wrong to leave them out. Jacksonville still needs to beat Tennessee to be assured of a division title, while the Titans would do nothing but potentially harm their 2026 draft position with a victory.
Cincinnati Bengals (vs. CLE)
Unlike the Vikings and the Jaguars, the Cincinnati Bengals have, once again, been hamstrung by their atrocious defense this season. However, streaming is about matchups, and defenses rely on turnovers, rather than keeping the score down.
That’s why, if the Vikings and Jaguars are taken, the Bengals make a great one-week rental in a dream matchup against the Cleveland Browns. The Browns’ offense ranks dead-last in the aforementioned PFSN Offense Impact metric, and has committed multiple turnovers in each of its last six games.
In fact, six of the last eight defenses to face Cleveland have finished in the top seven in fantasy that week. The Bengals’ defense has been inconsistent in fantasy, but matchups don’t get much better than this one.
