The St. Louis Cardinals have clearly had some success in the trade market over the years. Recently, guys like Nolan Arenado and Paul Goldschmidt have been the big-name trade pickups. Goldschmidt is no longer in town after signing with the New York Yankees as a free agent, but Arenado is still impacting the team day in and day out. The Cardinals actually have had a lot of success adding stars to the organization through the trade market.
