Salary Cap

How does everyone manage the salary cap?

I was just starting to get a team full of promising rookies but then I didn't have the cap to pay them once they came out of their rookie contracts so has to try and trade them but didn't get great picks so it's like I had to start over again. For context I'm about 10 seasons in and haven't had a winning season so I'm not that great at the game 🤣🤣.

I really enjoy the game but it's seems almost impossible to progress.
