With John Mozeliak's departure from the St. Louis Cardinals, the organization is undergoing its first change in leadership in 18 years, and the significance of that is hard to overstate.
Yes, ownership remains the same, and the market that the Cardinals reside in funnels that into a certain style of operation, but regime changes typically happen fairly often in the game of baseball, so it is extremely rare to have one voice lead the organization for as long as the Cardinals have.
Chaim Bloom, who has taken the reins from Mozeliak after two years of serving as a consultant, brings in a wealth of knowledge and experience from his time running the Boston Red Sox and his over a decade-long run helping shape the Tampa Bay Rays into the machine they are now.
