The FCP heavily drains your stamina not the stamina of the opposing team. But if his stamina is great he will perform better late game then if it was not so good. But i would not focus too much on stamina...
Why not? It is a serious detriment to playing a FCP.
Also, I disagree that it is better to play a FCP when you are stronger than your opponent. In fact, there is almost no time when you should play a FCP.
Now, if you really want to play one, the best thing is to have a great outside d (as described above). However, you also want your forwards to have as high of an outside d rating as possible. They are the ones who will force most of the turnovers, provided the forwards on the other team have bad handling skills.
