If I recall correctly any team with decent handling/passing will break through full court press. I never use it unless against a team which I will get a landslide victory against. Usually full court press run and gun (and if they do the same, it's pretty chaotic, you'll see All-star Game scores (can hit like 150 points a game) but at the same time, you'll concede much more than usual.
A friend of mine say it's like Russian Roulette. So use it at your own risk, it can be fun, but it's definitely not the best defense to use.
