Something special happened in South Dallas last winter. First, coach Leonard Bishop's boys' basketball team completed its season with a 40-0 record and the state Class AAAA championship. But that was just the beginning of the good news. Soon after, the growing list of national schoolboy rankings, led by the prestigious USA Today and Prep Hoops USA polls, added to the accolades. Lincoln became the first Dallas schoolboy team ever to be selected the No. 1 team in the nation.
