After the departure of Tony La Russa and Albert Pujols, the St. Louis Cardinals needed to re-tool their lineup and rotation in order to have a chance at defending their World Series title. La Russa's departure was filled by the youthful and inexperienced Mike Matheny, who, as expected, retained much of La Russa's staff. Matheny will need their experience and support as he ventures into his first managing position. Pujols' departure shocked Cardinals Nation; however, as soon as the decision was made, John Mozeliak went to work to replace him.
This appears to be the answer to the question: What now after Pujols?
