Cardinals GM John Mozeliak has been a popular man in St. Louis since casting the squad that won the World Series last fall.
Overall, Mozeliak has done a good job after taking over for Walt Jocketty in October of 2007. The 43-year-old GM sports a 420-351 regular season record (as of 8/22/2012), with one NL Central title, two playoff appearances and a World Series ring.
Mozeliak took some heat for his trade of Colby Rasmus for pitching help last summer, but there is no doubt the Cardinals would not have made it to the Fall Classic without his creativity.
