Joe and Williams both won state championships at Fort Smith Northside, just not together in their lone season with Joe a senior and Williams a sophomore in 2018. Together, they took the Grizzlies to the Class 7A state championship game, losing, 64-51, to North Little Rock.

Williams and Joe held an NBA championship parade on Wednesday in their hometown of Fort Smith, AR. The two teammates have been tied at the hip at every level. They were high school teammates and attended college together at Arkansas. For the last three years, they've been on the Thunder as well.

Mayor George McGill officially proclaimed July 24, 2025, to be "Jaylin Williams and Isaiah Joe Day" in the city during the "Thunder in the Fort" event held Thursday.
