Fantasy Football Defense Rankings for Week 2

Fantasy Football Defense Streamers for Week 2

#3 - San Francisco 49ers (48% rostered)
The San Francisco 49ers get an ideal matchup this week against the New Orleans Saints. They are expected to be one of the worst offenses this season and Spencer Rattler is arguably the worst starting quarterback in the league. He failed to record a touchdown last week, and considering the 49ers posted a sack and two trunovers in their first game, they are an excellent streaming option.
#2 - New England Patriots (14% rostered)
The New England Patriots will face off against the struggling Miami Dolphins ion Week 2 of the 2025 fantasy football season. Tua Tagovailoa threw two interceptions and was sacked three times last week, so the Patriots should have plenty of scoring opportunities, especially since they already produced four sacks and an interception of their own last week.
#1 - Los Angeles Rams (17% rostered)
The Los Angeles Rams defense recorded three sacks and two turnovers last week on their way to a DST3 finish. They also didn't allow a single touchdown and get an even more favorable matchup against the Tennessee Titans this week. Rookie Cam Ward suffered six sacks in his first game and should have his hands full with Rams' aggressive style.
