5 cornerbacks 49ers can't afford to ignore in the 2025 NFL Draft

Another Big Ten standout, Sebastian Castro is in his senior year at Iowa. He forced a fumble in the monstrous shutout against Illinois State.

He, too, recorded three interceptions last year. Just like Will Johnson, the Oak Lawn, Illinois, native returned one for a touchdown in 2023.

Castro had eight passes defended last year. In addition, he was responsible for another forced fumble and a sack.

As San Francisco may need to replace Charvarius Ward and/or Deommodore Lenoir, this collegiate athlete is a viable option. He could be available on Day 2.

Castro may be just under 6-foot, but he packs a punch for his size. A very aggressive and physical defensive back like this one can make the Niners secondary a threat next year.
