unfit
This term carries a strong sense of inadequacy, whether referring to a lack of moral character, professional competence, or physical stamina. When applied to a person's role, it suggests a fundamental mismatch between their capabilities and the demands of the position, often implying a judgment of failure or disqualification. In a physical sense, it describes a state of bodily deterioration or a lack of athletic conditioning. Unlike being injured, being unfit implies a chronic lack of preparation or health that prevents one from performing physical tasks efficiently.
