Harkey is a practical late-round bet: a college tackle with enough quickness and toughness to see whether he can become a guard. He has already navigated several programs and earned a job at Oregon. The Chargers do not need him to start tomorrow; they need him to learn the interior nuances and become dependable depth.
Strengths: Athletic movement, tireless hands, substantial college starting experience and position flexibility. His path through multiple programs suggests resilience and adaptability.
Weaknesses: He is changing positions and must improve his anchor, leverage and ability to sustain blocks inside. His NFL role is developmental until those technical issues are resolved.
