By paying them out, you instantly cut your salary cap and the amount of $$$ we can spend on the replacement.
It's just not as simple as paying them out and getting someone better in. With your logic, they would need to be better but cheaper because a portion of their salary was used up to make room for them.
The point is, you can't do them all at once all you eat your salary cap up paying them out and replacing them. Then you are still trying to fill the gaps left by the guys that haven't had their contract renewed.
