Rushing and Ball Carrying
Running backs are responsible for taking handoffs from the quarterback and running with the football to gain yards. They follow their blockers and try to find openings in the opposing defense. Success is measured in yards gained and touchdowns scored. Even though passing plays have become more common in the NFL, rushing still remains an important part of most offensive game plans.
Receiving and Pass Catching
Modern running backs spend significant time catching passes from the quarterback. They run short routes and catch passes in the flat, in the slot, or even out wide. This skill allows offenses to use running backs as receivers, making them harder to defend. Good hands and the ability to run routes are now essential skills for running backs at all levels of football.
Blocking and Team Contribution
Running backs are expected to block defensive players to protect the quarterback and create openings for teammates. Blocking might not appear on the stat sheet, but it is crucial to offensive success. Running backs must block linebackers, defensive ends, and other defenders who rush toward the quarterback or run toward the ball carrier.
Changes from Past Decades
In earlier eras of the NFL, running backs were primarily used to carry the ball. Today, teams value running backs who can do multiple things on the field. The increased emphasis on passing and quick offense has changed how running backs are used. Many offenses now rotate multiple running backs depending on the situation, with some specialists in rushing, others in receiving, and some who are good at both.
Importance in Modern Offenses
Running backs remain important to modern NFL offenses, though their role has evolved. They provide balance to offensive attacks that rely heavily on passing plays. A strong running game can help control the game clock, move the chains on offense, and take pressure off the quarterback. Teams that have effective running backs typically have more successful offenses overall.
