You have to go into a post. To do this you have to hold the Left Trigger while pushing your left stick at the other player. Then just push you right stick in the direction it says.
If you didn't understand what I just said go to the tutorial section in the menu, then scroll over to post offense and it goes step by step on how do do all of the moves that you need in the drill. Trust me I sat there for about 1/2 hour before I thought of looking up the tutorial. Good Luck!
