Here are some thoughts
1. H delivers the ball to the basket from a diversity of unusual places, which greatly expands his ability to deliver it from places that the defender is not. Think Kevin McKale here. Okay, you are too young. An example: with his chest in the other guys, he will reach back and out with a bent right arm and use what might look like a throwing motion to score the ball. It covers a lot of ground (he is extremely wide through the shoulder area) and he can modulate the distance from his body if the defender reaches to react. He thus is able to draw slapping fouls and then continue with a very repeatable and reliable delivery. There are other such deliveries.
2. Everyone assumes that you have to be there first. Like me, H figured out at an early age that you just need to be there at a different time. Defenders can only move as fast as the offensive player; does them no good to be able to move faster. Then, a change of pace, quickness if you will (which Hansbrough is exceptional at), favors H greatly. He creates a gait in the defender and then, uses his footwork to catch the defender between steps to change direction and pace; no matter how much a better "athlete" the defender might be, his momentum must settle first before he can react. Too late, sorry. Then, he reacts with an explosive burst, H lets him pass by, and voila, he has a clear look. Being there at a different time, is even better than being their first because being their first makes you subject to swats out of the air; H has the guy past him when he shoots; no opportunity for recovery then.
More later, but these two are undervalued today. Think a big strong Earl Monroe, not an MJ, or Kobe, or Labron.
