“The league relocated farther south to Nolensville, with an agreement it would keep the name South Nashville Little League for three years. That agreement expired in 2020, and the league's board changed the name to Nolensville Little League. Thus, new uniforms were needed. The coaches came up with the idea to model the uniforms after Vanderbilt, a hometown team to which Nolensville players looked up and whose uniforms they loved. The presence of the Browns didn't hurt, either. Scott Brown’s son has been involved with the Nolensville Little League all-stars since fall 2019.”
