Miami claimed JuJu Brents off waivers, boosting a thin cornerback room with a high-upside flier who battles a serious injury history. Brents, a 6-3, 189-pound playmaker with 34-inch arms, plus elite agility, joins Rasul Douglas, Jack Jones, Storm Duck and Jason Marshall Jr. as a measured bet for the future. A former Colts second-round pick, Brents has rookie tape of promise but an injury-shortened profile that makes Week 1 unlikely; still, health sparks a potential long-term contributor in a talent-poor group.

Injury disruption aside, Brents carries tantalizing traits for Dolphins coordinator Anthony Weaver to mold. If he can stay on the field, his length and movement could unlock his ceiling and eventually push for outside roles, complementing the young, rising corners in Miami.
