Couch has spent two full seasons on Buffalo's practice squad without ever appearing in a regular-season game, which puts him squarely in long-shot territory heading into year three. His size (5-foot-10, 175 pounds) points him toward a slot-corner role if he ever gets a real look, but for now he's purely developmental depth behind Buffalo's established corners.
Strengths: Versatile frame that projects to both inside and outside cornerback roles if he earns more defensive reps.
Weaknesses: Has not played in a single regular-season NFL game across his first two seasons in Buffalo.
