Allen has a straightforward rookie calling card: get the hard yards, fall forward and make short-yardage snaps unpleasant for defenses. He also has better patience and vision than the bruiser label suggests. The path to more than that depends on proving usable in protection, coverage units and the passing game.
Strengths: Power through contact, low center of gravity, patient lane development, and a productive college rushing résumé.
Weaknesses: Limited verified NFL receiving and special-teams value, plus only average long-speed, can narrow his early role to physical run situations.
