I believe Mason Rudolph has been with the Pittsburgh Steelers since 2018. He was a third-round draft pick in that year and has since become a regular on the team's roster. Mason Rudolph has seen a lot of success during his time with the Steelers, particularly in the past two seasons where he has shown tremendous growth as a quarterback. He is a valuable asset to the team and is expected to continue playing a key role in their future success.
