I wish that you would be able to trade points with players, so you can even out some trades. When you trade points, you lose cap money, resulting in less cap space.
And when signing free agents, you could have like a 10-day contract or 5 game, etc. And if you liked the way they performed, you could sign them for a year. A prompt would pop up saying the contract is over asking if you want to resign, trade, or release.
