Every NFL team's personnel makeup is different. The Ravens and Eagles are stockpiled with playmaking tight ends. The Saints have quarterbacks who can contribute in different ways. The Browns have two talented running backs. NFL offenses aren't one-size-fits-all.
Finding success when you have the ball means playing to the strengths of your roster and playcaller.

Let's take a look back at the 2019 season and evaluate the offenses that excelled at 11 different personnel groupings, like we did last summer.
