Miami Dolphins Load Up Defense for Florida Playoff Run

MIAMI — The Miami Dolphins, South Florida's NFL powerhouse, have transformed their defense into a formidable unit with a flurry of offseason moves, signing veteran linebacker Ronnie Harrison as their 31st addition since free agency began. The one-year deal, likely at league minimum given the team's $2 million cap overage, brings Harrison's 52 NFL starts and hybrid safety-linebacker versatility to a unit craving depth and leadership. Initially reported by WSVN 7News, the moves signal GM Jon-Eric Sullivan's push for competition amid limited cap space until June 1.[1] Projected starters highlight the revamped front: Zach Sieler and first-round pick Kenneth Grant at defensive tackle, flanked by edge rushers Chop Robinson and new signee Josh Uche. Backups include Jordan Phillips, Zeek Biggers and Matthew Butler inside, with Robert Beal Jr. and Cameron Goode providing edge depth. At linebacker, Jordyn Brooks, Tyrel Dodson and Willie Gay Jr. lead, backed by K.C. Ossai, while the secondary features Storm Duck and Marco Wilson at corner with safeties Dante Trader Jr. and Lonnie Johnson Jr.[3][4] Sullivan, speaking at the NFL owners meetings, outlined a draft-heavy blueprint with seven top-100 picks to build around premium positions and inject youth. Pre-draft visits like California cornerback Hezekiah Masses, a 6-1 prospect with 31.13-inch arms, underscore the focus on versatile defenders. Training camp at Hard Rock Stadium in Miami Gardens will test these additions against a roster blending veterans and rookies for a 2025 playoff charge.[2][7] Local fans, from Miami Beach to the Keys, see echoes of past contention as the Dolphins aim to contend in the AFC East. With competition at every spot — including challengers like Alex Austin and Darrell Baker in the secondary — the defense positions Miami for a deep run, strengthening the Sunshine State's NFL presence.[1][3]
