In my Opinion sir... your suggestion would definitely go against Buzzerbeater's push to have a healthier/higher standard of competition...
Please also try to understand this too that the NBA Salary Cap only involves the Players' Salaries:
https://en.wikipedia.org/wiki/NBA_salary_capIf there's anything we can suggest to make our Economy gain more is to incentivize the Scrimmages games...
and probably adding some concession food stands/items feature... that we can also Sell and adjust Prices for our Home Games... but I think it would be overkill...
