Fullback vs Running Back
A running back is usually the primary ball carrier. A fullback is usually bigger and more blocking-oriented, though fullbacks can still carry the ball, catch passes, and protect the quarterback.

Definition
A fullback is a back who usually aligns between the quarterback and tailback, beside the quarterback, or as an H-back. In college football, the role often centers on lead blocking, pass protection, short-yardage runs, and play-action looks from heavier personnel.
Example
In 21 personnel from the I-formation, the fullback can lead through the hole on iso, block the edge on power, leak into the flat after play action, or carry the ball on a fullback dive.
How to Interpret It
Fullbacks are less common in spread offenses, but they still matter for short-yardage packages, downhill run games, option teams, and offenses that use H-back or tight-end hybrids.
Common Comparisons
Fullback vs H-back
An H-back is a movable tight end or hybrid blocker. A fullback usually starts in the backfield, while an H-back may align off the line, in a wing, or across the formation.
How CFB Track Uses It
