John Schuerholz spent 26 years as a general manager with the Kansas City Royals and Atlanta Braves, the last 17 of those with his Atlanta until he was named club president in the fall of 2007.

His success with the Braves is well documented, but less known is the line of succession he had in place. During Schuerholz's last few years in Atlanta, his scouting director was Dayton Moore, who Schuerholz hoped would eventually take his place as GM. The two were so tight that Moore was nicknamed John Schuerholz Jr. by many of the Braves' employees. However, instead of waiting for Schuerholz to get promoted, Moore took the first GM opportunity he received, accepting an offer from the Royals to be their GM in 2006.

Enter Frank Wren. Wren served as GM of the Baltimore Orioles in 1999 after serving as assistant GM for the Marlins from 1991-1998. After a rocky relationship with Orioles owner Peter Angelos, they parted ways, but not until Bud Selig had to get involved to make sure Wren got paid for his services. Wren quickly landed on his feet, as he was hired by Schuerholz as assistant GM, a position he would hold for eight seasons.
