Interesting WaPo article on NBA G League team Ignite, where they have all 6 players that skipped college. Jalen Green is making $500,000 this year, expected to be a top 3 pick in the NBA draft. The NBA provides off court support, including providing scholarships to Arizona State. This seems like much more of a threat for college basketball not getting HS stars in the future than foreign leagues.
