Malnati,
"Unlike in Boston, where a full rebuild was not required, Eptein and Co. had to try and construct a championship roster from the ground up. He let productive but expensive hitters Carlos Peña and Aramis Ramirez depart after the 2011 season, dealt righthander Carlos Zambrano to the Marlins and traded 2008 first-round pick Andrew Cashner to the Padres in a deal that brought back Anthony Rizzo to be the team's starting first baseman. In July 2012 Epstein traded ace Ryan Dempster to the Rangers for a package that included minor league pitcher Kyle Hendricks. The Cubs dropped 101 games in 2012, their highest total since 1966, and 96 games in ’13, but all that losing that gave them top-five draft picks that they used to select Kris Bryant (No. 2, 2013) and Kyle Schwarber (No. 4, ’14)"
