Yes, the 7'0" Towns is tall and tried basketball in high school. He was quite successful, getting a scholarship to Kentucky before becoming the No. 1 pick in the 2015 NBA draft.
As a two-time NBA All-Star and third-team All-NBA player this past season, the 23-year-old would've probably given the recreational league team a nice boost if he had agreed. Unfortunately, he's busy preparing for the 2019-20 NBA season.
You have to give the person credit for attempting to find a new teammate, but he might want to try googling first.
