The Memphis Bulls evolved from the Wanderers around 1973 when they gained a sponsorship from the Schlitz Brewery… and thus the bull.

Ken “Mad Dog” McBride with the ball of the day. All Leather.
Some did not like leaving the Wanderers and returned to the maroon and white jerseys to form the Wanderers II.
Tom Baker had a connection with the Jack Daniels distillery and the financial support spurred the team to make a sponsor change. The Bulls changed their name to Old#7 and their colors to green and black to support Jack Daniels.
