Back in the day, the fullback was the high school team stud. He always played both ways, usually at middle linebacker on defense. He ate raw meat. Nobody messed with him. Rumor has it that Bear Bryant liked to recruit fullbacks to Alabama. He liked their toughness, their meanness. Once in Tuscaloosa, they put on weight and played on the line. He reputedly sought high school quarterbacks to play in the offensive and defensive backfields. Best athletes, he thought.
We don’t really run across fullbacks anymore. There isn’t one listed on the 2022 Ohio State roster, nor on the 2022 Georgia roster nor even on Army’s 2022 roster, and we know that they use fullbacks in their option game.
