Campbell is the kind of reserve coaches lean on because he helps every phase. He can cover kicks, play multiple spots and keep the back end organized when injuries force a reshuffle.
Strengths: Special-teams experience, defensive-back versatility and reliable assignment discipline create real game-day value beyond pure depth-chart status.
Weaknesses: He is not a high-end one-on-one coverage athlete, and a larger defensive role would test his consistency against top receiving talent.
