The Pittsburgh Steelers very briefly at the start of the 2019 season dabbled with the use of the pony backfield with James Conner and Jaylen Samuels, but this came to a screeching halt after Ben Roethlisberger was injured in the middle of the second game of the season.
They weren’t the only team in the AFC North interested in exploring this idea, however, as the Cleveland Browns also made use of it after Kareem Hunt, whom they signed as a street free agent last offseason, returned from his eight-game suspension. They put him on the field at the same time as Nick Chubb, a young Pro Bowl back, with the pair even showing the willingness to block for one another.
