If you're going to have some sort of NBA minor league arrangement, the owners are going to insist on two conditions:
1) players assigned to the D-League don't make as much as NBA players
2) time in the D-League doesn't move the clock to get players closer to unrestricted free agency
The model, once every team has a D-League affiliate, could possibly be to treat roster cuts assigned to the D-League like the NFL practice squad, with the opportunity to earn a bigger salary than other D-Leaguers, but with limits on how long they are eligible. To compensate teams for investing in these players, other teams would only be allowed to poach them with full contracts and not ten-day contracts.
