Defending the face up
 

Whats the best way to defend the likes of Amare Stoudamire, Dirk, Bargnani of the world when they face up? If you put you hands up (with the right stick) it seems to be a quick blow by or if you anticipate the J and try to block its game over. Is there a way to put one hand up like you do on guys on the perimeter when they shoot a jumper?
