it would bring me a big advantage to those who do manage their cash well and make the right investments..
But that is part of any manager game. Why should a team that fails to plan their team accordingly be on the same level as one that have planned well? At the end of the day, this game is a basketball manager simulation.
The only thing that needs to be sorta addressed is the transfer market. Thats where the sharemarket analogy comes in. Teams have been screwed by the fluctuations of prices the transfer market through no fault of their own. They have no control over it and hence you can't really plan and manage and budget for it which throws out the whole manager concept.
