Los Angeles Rams have the best defense in the NFL this season. They have the best defensive player in the league in Aaron Donald, and their secondary is really solid as well. They can shut down the run and the pass, and they’ve been dominant in most of their games this season.
I think the Tampa Bay Buccaneers have the best defense in the NFL this season. They have a really strong front seven that can stop the run and get after the quarterback, and their secondary has been playing really well lately. Plus, they have a lot of experience on defense, with players like Lavonte David and Ndamukong Suh leading the way.
In my opinion, the Pittsburgh Steelers have the best defense in the NFL this season. They have a great pass rush, led by T.J. Watt, and a solid secondary that can cover receivers. Plus, they’re very good at forcing turnovers, which is always key in winning games.
