For many years, carrying seven linebackers on the roster was part of the norm. However, the game has become increasingly pass-heavy which means teams are less likely to run the ball. With the evolution of the passing game in the NFL, every team’s base offense features three starting wide receivers. Also, the fullback position is essentially non existent these days as teams rarely carry one on their rosters. Due to teams running the ball less and less, the need to start three linebackers is not necessary. In fact, starting just two linebackers is effective in today’s game where offenses are trying to put as many of their best athletes on the field at the same time to create mismatches.
