Regardless of his draft position, Bagley's primary source of income for his first several years in the NBA will be from his Puma endorsement.
https://www.google.com/amp/s/www.cbs...with-puma/amp/According to The Athletic, Bagley's five-year contract will be the richest rookie shoe deal since the one that Kevin Durant signed with Nike back in 2007. That went for seven years and $60 million (Durant was offered $70 million from Adidas, but turned it down), so we can expect the numbers on Bagley's deal to be similar.
