Miami’s defense just got a jolt from an unexpected source: rookie Jason Marshall Jr. Despite never playing nickel before, Marshall stepped up after Kader Kohou’s injury and made a real impact in preseason. Coaches and teammates are buzzing about his physicality and quick learning, especially after a standout play against Detroit. If Marshall keeps this up, he could change how the Dolphins cover the slot and force some tough roster decisions. With Miami banking on its young talent this year, Marshall’s emergence is a big deal. How do you feel about rookies stepping into key roles so quickly? #Sports #Football #MiamiDolphins
