Taylor Street was the powerhouse crew from the 1940s until 1975. They literally controlled Chicago. They, as a standalone entity, were probably more powerful than the rest of the Outfit combined. They also controlled the political machine and the Connection guys. At some point, the Connection guys (Humphries, Alex, Patrick, Larner) were reassigned to the Rush Street crew.

At that time, Taylor Street controlled not only their Chicago territory, but had guys in Las Vegas, Los Angeles, San Diego, Arizona and Florida.
