The game defensive AI is inconsistent so you'll have to do it yourself. Do just like you would in real life. The lowest defender on the weakside will "bump" the roll man then recovery to his man. Works better in real-life or against another human better than the computer (real-life it means a guy has to throw a pass over the top of the defense across his body, against humans in 2K it means they have to see the open man then throw the pass). the computer doesn't always acknowledge how tough that pass is, so at times you'll see a guys like Michael Carter Williams throw it as a perfectly placed chest pass. -_-
