It may finally be time to update the old adage, "defense wins championships." The NFL has implemented quite a few rule changes over the past couple years, and a vast majority of those changes seem designed to benefit the offense. As a result, NFL teams averaged 23.3 points per game this season, which is the third highest mark ever and a massive increase from the 20.6 points that the league averaged in 2005. 

Today's NFL seems best-suited for teams that put points on the board, as teams with an offensive-minded head coach were extremely successful this year. 

Entering 2018, there were 18 teams run by an offensive-minded head coach, and nine of those teams made the playoffs. While that doesn't seem particularly impressive, consider the fact that only three of the 14 teams run by defensive head coaches made the post-season. And that stat includes Baltimore Ravens' coach John Harbaugh, who really made his mark as a special teams coordinator.

The NFL is notoriously a copy-cat league, so it should come as no surprise that most NFL teams with an opening are clamoring to hire someone with an offensive background. Of the five teams that have hired a new head coach this offseason, four have chosen coaches with an offensive background. And NFL teams seem particularly desperate to find anyone who's so much as made eye contact with Los Angeles Rams' coach, Sean McVay. 

Logically, this hiring trend makes sense. And it shows that teams can adapt to a changing landscape, which is more than you could say about many NFL owners in the past. However, the desire to hire the next Sean McVay could lead to a lot of boom-or-bust signings, as teams seem willing to forego experience in favor of offensive innovation. For example, we've already seen Kliff Kingsbury and Freddie Kitchens get head coaching jobs, and neither coach has spent more than half a season as an offensive coordinator in the NFL. 

All in all, it seems like the NFL's offensive revolution is here to stay. But whether or not the recent obsession with offensive-minded coaches will work out long-term, remains to be seen.
