David DeCastro, an All-American at Stanford, was selected by the Pittsburgh Steelers as their First Round (24th Overall) Pick in the 2012 Draft. Unfortunately, he was only able to play four games as a rookie due to an injury, but he has been relatively healthy since then. He played at Right Guard until the end of the 2020 Season. In 2015, DeCastro was chosen for the Pro Bowl, and he continued to earn that accolade for six consecutive years. Additionally, he has been a First Team All-Pro twice.

However, DeCastro sustained an injury that kept him out of the entire 2021 Season. As a result, the team released him, and he subsequently retired. Despite this setback, DeCastro will be remembered as one of the better Tackles in Steelers history.
