I agree with every word the professor said, and it can’t be said often enough.
The only time CPA is a good choice is if you know you have good players but you need money fast. And then it is a temporary measure to help you get on your feet. Like a loan, it’ll cost you. And at that juncture, you should try for a deal that is part CPA and part percentage. That will give you some instant cash but you still benefit from the quality of your players.
Like the professor said, one party always loses with CPA.
