The G League is creating a new venture as an alternative to the current one-and-done route for the best American basketball prospects.

As part of a newly formed "professional path" starting in the summer of 2019, the G League will offer "Select Contracts" worth $125,000 to elite prospects who are at least 18 years old but not yet eligible for the NBA draft.

The rule will target recent or would-be high school graduates who would otherwise likely spend just one season playing college basketball. They will receive a six-figure salary and benefit from the NBA's infrastructure.

Without the restrictions of the NCAA's amateurism rules, players will also be free to hire agents, profit off their likeness and pursue marketing deals from sneaker companies.

While changes to the NBA's age limit likely won't be implemented until the 2022 draft, the league considers this an immediate response.
