In 2022, Kevin O'Connell's first year as head coach, the Minnesota Vikings made the playoffs in spite of Ed Donatell's "bend and eventually break" philosophy as defensive coordinator. So it was not a surprise when O'Connell did a 180 with Donatell's replacement when he hired Brian Flores.
The Vikings' defense naturally improved some in Flores' first season as defensive coordinator. Then last season, the Vikings led the league in takeaways, along with being top five against the run and in points allowed.
The Vikings' defense should be pretty good again this season, fueled by Flores' unpredictability and blitz-heavy tendencies.
