Whenever I play NBA 2k12/NBA 2K13, I make sure my Total Control is turned on, so I can control my off ball players

So that's how he's probably doing an Inbound Alley Oop

For example, I have Dwight Howard as my center and Metta World as my inbounder, I switch to Dwight Howard by holding down his corresponding button then run towards the basket, while running towards the basket, I press the pass button

Voila! That's it
