Mid-Season 2025 Mock Draft: The Saints build up the trenches

4:104- Sebastian Castro, S, Iowa

The Saints need to continue building out their defensive back room, especially with the questions surrounding Paulson Adebo’s future. Selecting Sebastian Castro in the fourth round would help ensure depth at multiple positions. Castro is a chess piece whose impact can be felt at multiple positions.

Sebastian Castro has been used everywhere in Iowa’s defensive secondary, playing safety, corner, and even some linebacker. Having this versatility will allow him to fill a role that has been vacant ever since the departure of PJ Williams.

Castro is a high IQ player who is instinctive and decisive, especially in the run game. Once Castro sets off to the target, he becomes a missile, quickly seeking out the ball carrier. His physicality ensures that he finishes the play once he gets there. His contributions in the run game are one of the best spots of his game.

Castro is one of the oldest players in this year's class, already turning 24. He also doesn’t contain elite athleticism and top end speed, causing problems when he is matched up against quick, twitchy receivers. He will need to improve his agility for him to be used in man coverage against those matchups.

Ultimately, Sebastian Castro is a player who can be a chess piece in any defensive secondary. His versatility makes him a compelling prospect for teams who need to improve their depth.
