This game isn't meant to simulate real life, the sooner you realize that the easier the game becomes to accept. After playing (sparingly) BB for 5 years I can tell you it is far from real life. Nothing besides the game simulator is really a great simulation of basketball management. I know BB isn't looking for ways to give you more money, the market is inflated as it is.
But real life logic doesn't exist here. For example:
Players don't get trained and get better on Fridays at 6 server time and suddenly play better after that.
Salary isn't increased by how skillful a player is, but how well he plays.
T.V. contracts in real life aren't the same for entire leagues.
