ITTL the Rams spent 33 seasons at the Memorial Coliseum (1946-78). In 1979, they opened MCA Stadium in Chavez Ravine on the same parking lot as Angel Stadium (on the OTL site of Dodger Stadium). As a result, Anaheim Stadium, home to the MLB Hollywood Stars ITTL, has remained a baseball only park. MCA had the naming rights because they were the Rams' parent company at the time.
In 1992, Lew Wasserman was appointed commissioner of Major League Baseball. To facilitate his new job, Wasserman sold the Rams to Dr. Jerry Buss. Also included in Buss's group were Steven Spielberg, Magic Johnson and David Geffen. In 2004, Geffen would sell his stake when he was offered the rights to a World League expansion franchise that eventually became the Berlin Ogres.

When the football Cardinals moved to Arizona in 1988, St. Louis would not be without pigskin for too long. In 1994, the struggling Raleigh-Durham Skyhawks of the World League moved to St. Louis to become the Stallions. The Stallions played at the second Busch Stadium (next to Riverfront Square) for the first two years before moving into the Trans World Dome (now the Edward Jones Dome) in 1996.
A decade later, the New Orleans Saints played the 2005 season with six "home" games in St. Louis because of Hurricane Katrina. At first, there were some who thought the Saints would settle permanently in St. Louis until actor Gus St. Pierre led the NOLA Strong campaign to persuade owner Tom Benson to keep the Saints in Louisiana.
A year later, Stan Kroenke bought the Jacksonville Jaguars and moved them to St. Louis to become the Sorcerers in 2007. In exchange, the St. Louis Stallions of the WLAF moved to Jacksonville and became the Tomcats.
