The Pittsburgh Steelers voted on five players to be their team captains in 2020. Quarterback Ben Roethlisberger and center Maurkice Pouncey represented the offense. Defensive lineman Cameron Heyward and outside linebacker T.J. Watt were voted captains of the defense. Safety Jordan Dangerfield was their special teams captain.
Of the five, only Roethlisberger and Heyward retain their captaincy entering the 2021 season, as voted on by their peers. Pouncey is retired, while Dangerfield was not retained (he was replaced as special teams captain by Derek Watt).
As for T.J., for whatever the reason, he was not voted a captain this year.
