The Read: Johnson is the type of veteran back who can look invisible in a shallow box score until the offense needs a blitz picked up, a checkdown turned into a field-flipper, or a tired defense punished by a one-cut runner with real juice. The fantasy ceiling is role-capped behind Buffalo’s lead backs, but the utility is not imaginary. He is a passing-game pressure valve with enough burst to make defensive coordinators hate the small print.
