Fantasy football defense rankings for Week 4 offer crucial insights for managing your lineup. Here's a breakdown from the elite defensive options, like the Raiders, to the more streamable choices, such as the Vikings, ensuring you make the best decisions for your team.

**Elite Defenses**

The Raiders' defense has been a standout performer this season. Their defensive line has consistently pressured opposing quarterbacks, and their secondary has been adept at creating turnovers. Starting the Raiders this week is a no-brainer, especially given their favorable matchup against a struggling offensive team.

**Solid Options**

Several other defenses fall into the solid category, reliable performers that can anchor your fantasy football setup.

1. **Bills**: The Buffalo Bills continue to demonstrate strong defensive stability, particularly in their secondary, which excels in pass coverage.
2. **Buccaneers**: Tampa Bay's defense is formidable, anchored by exceptional linebackers and a strong pass rush. They're a top option against most offensives.
3. **Packers**: Green Bay's defense is notably balanced, capable against both the run and the pass. They also have a decent schedule this week, making them a strong play.

**Good Streaming Choices**

For those looking to stream defenses, several teams offer good potential in Week 4.

1. **Cowboys**: Dallas has shown flashes of brilliance defensively. If they continue to perform and capitalize on turnovers, they will be a sneaky good option.
2. **Seahawks**: While inconsistent, Seattle's defense can exploit weaker offenses. They’re a viable consideration if your regular defense is on a bye week.
3. **Vikings**: Minnesota's defense is also an interesting streamable choice this week. Although they aren't the most formidable, they are good enough to take advantage of a favorable matchup.

**Teams to Avoid**

Some defenses might be tempting based on name recognition but are better left on the bench this week.

1. **Giants**: New York’s defense has struggled with consistency, making them a risky play this week.
2. **Lions**: Detroit’s defense has been porous, especially against high-powered offenses. Consider alternatives if available.

When crafting your fantasy football defense strategy for Week 4, considering these rankings can help ensure optimal performance. An elite defense can make the difference between a win and a loss, while a well-chosen streaming option can maximize your points during critical matchups.
