The salary cap for your team is 40 million (40000K). Once you run out of money, you can’t acquire new guys. The only way you can get cash is to make a trade where the other manager is willing to give you excess money…which can be hard to do. So, really pay attention to your draft salary caps so you have money left over to get through 162 games.
Generally, during the draft, you definitely don’t want to spend all of your salary cap. I tend to have around 10 million or so left. It will probably bite you in the butt at some point.
