This trading method if done correctly can make you a lot of profit. It is hard to do efficiently consistently but something you should always be looking to take advantage of.  Basically think of it like this, you trade a player away with a lower overall for a guy who is a higher overall. You keep this process up and walk up the ladder until you have reached a huge profit or a good enough profit. It is like starting out with a penny and turning that into a dollar.
