Big-bodied, disruptive interior anchor with NFL-caliber upside
Castillo is a 6-foot-4, 270-pound Northwestern commit with the frame and strength profile to hold up inside and impact the run game early. His main differentiator is size-plus-power: he projects as a sturdy, physical defensive lineman who can eat blocks and create leverage, which is valuable for teams looking for interior toughness rather than just splash plays. Public scouting listings identify him as a strong-side defensive end prospect, and his profile suggests a fit for a defense that values gap control, motor, and physicality.
