2022 could be the tsunami for all of college basketball.
This G League thing is just a small wave. It's probably not enough, unless the player just really, really, really hates even the idea of school. One and done is the proven path, so most guys will stay on it.
If they allow players to go straight from HS directly into the real draft, not just the G League, that's a game changer, because now an 18 year old can gamble on being drafted, and even if he's not, he has 125K waiting for him in the G League.
It will be especially acute if the NBA negotiates a multi-year either/or with the player's association in 2022- a player can either enter the pros at 18, or he's not eligible for the draft again for 2 or 3 years. If they go that route, college basketball as we know it is gone.
