The St. Louis Cardinals have not typically been major players in the free agent market since 2010. The team tends to be much more active in the trade market as Paul Goldschmidt, Nolan Arenado, Marcell Ozuna, and Tyler O’Neill all came to the team via trade. As a result, they are not too many options from which to choose the best free agent signing since 2010, though there are still some key players.
