It doesn't make sense that my local club team could buy an NBA player (even if it's for a short time) because the NBA teams won't sign him due to his salary being too much.
Youre local club could buy any uncontracted nba player if they want to go broke. And the nba are currently going through a shortened season due to players striking because their contracts are higher than the franchises can maintain...
Still, this does point out the same issue in this game. Maybe a hard salary cap would help regulate excessive salaries and balance out the difference between the top teams.
