When Nike took over the NBA apparel contract, they afforded teams more flexibility with their jersey designs. The Los Angeles Lakers expanded on that by using the City Edition to create a Lore Series in which franchise icons would create a custom design for a particular season.
It began with the late Kobe Bryant transforming his Black Mamba persona into a uniform for the 2017-18 season, and his design was brought back while the Lakers made their championship run this year.
Then for 2018-19, the Lakers handed the design canvas to Magic Johnson, who of course helped lead the team to five championships and at the time was the head of their front office as president of basketball operations.
