Conventional wisdom advocates selecting a fantasy football defense with one of your two final picks. Others might punt the position until the end of the draft in favor of a treasured sleeper and instead pick up a new defense each week, depending on who has the most favorable matchup. By streaming defenses in this way you can focus on the weakness of the opponent rather than a unit’s own strengths.

The key to this strategy is to roster defenses playing against teams that are either at a disadvantage in the trenches or aren’t expected to win many games, which means you can expect those offenses to play from behind more often than not, making them more predictable and prone to mistakes. For example, over the past three seasons, a team that trailed by four to 10 points passed the ball more than half the time with higher interception, sack and fumble rates than those teams leading by four to 10 points. Teams with offensive lines expected to struggle include the Cincinnati Bengals, Los Angeles Chargers and Washington Football Team.

In 12-team leagues, an average of 15 defenses are being drafted, according to data from Fantasy Football Calculator, leaving 17 to choose from during the early parts of the season. Not all of those are fantasy viable but there are plenty of opportunities to make the most of a mismatch each week.

One defense overlooked in this year’s draft will be that of the Washington Football Team. Washington’s defense has been more sizzle than steak these last few years, yet this season it warrants optimism. New head coach Ron Rivera and defensive coordinator Jack Del Rio switched the base defense from 3-4 to 4-3, brought in free agent cornerback Kendall Fuller and drafted edge rusher Chase Young to complement fellow first-round picks Jonathan Allen (2017), Da’Ron Payne (2018) and Montez Sweat (2019) plus veterans Ryan Kerrigan and Matt Ioannidis. Pro Football Focus ranks this defensive line as the third best headed into 2020. In Week 5, Washington will battle the Los Angeles Rams (25th best offensive line). In Week 6 and 9 they will face the New York Giants (20th). In Week 15 Washington will play against the Seattle Seahawks (28th).

Here’s how you can stream defenses for the those weeks and also the rest of the season.
