Steelers signed S Sebastian Castro.
The diminutive Castro (5’11/203) comes from Iowa’s well-reputed defensive back program, playing with good instincts and tenacity, but lacks ideal NFL size and athleticism (4.48 RAS) and is unlikely to lock down a starting free safety gig. Castro is best suited to the type of slot-safety hybrid role that earned him third-team All-American honors in 2023. Including regular and postseason play that year, Castro totaled 59 solo tackles, 36 stops, 14 TFLs, eight forced incompletions and three interceptions. He may have to work his way up from special teams, but his rapid processing in coverage should get his position coach’s attention.
