Player: S Sebastian Castro
Stock Value: Purchased
Reasoning: The Steelers didn’t hesitate to put in a waiver claim for S Sebastian Castro, whom they signed this offseason as a college free agent. Having spent the early portions of the season on the practice squad, Castro signed with the Buccaneers to their 53. Pittsburgh was surely paying attention, though, hoping Tampa might let him go again. They reportedly intended to re-sign him to their practice squad, so the Steelers signed him to their 53. In a corresponding move, they waived veteran S Juan Thornhill, whose play was not “up to snuff”.
