Scheme-dependent safety who plays with chaotic energy near the line of scrimmage. Castro might lack the man-cover skills and athleticism to remain a big nickelback in the pros. He plays with urgency from short zone and rushes downhill to set a contain edge and spackle missing run fits as a run defender. Athletic testing will be key in projecting Castro’s usage. A lack of versatility and his age (turns 25 in October) could work against him in the draft, but his physicality, field demeanor and special-teams utility create roster value in his favor as a down safety.
