It was always talked about Hendricks amazing power, how he would KO people with just one punch, seemingly just touching them and they'd be out, but I think there's a misconception here.
In the gifs below all of the people he's putting out with one punch are in an extremely vulnerable position, he makes them move back, get them off balance, and when he hits them there is nowhere for the energy from the punch to travel, so of course it shakes their brain badly, but I think any pillow fisted WW would be able to do that, given these variables (Hendricks is not pillowfisted though, just nothing special).
Leaning back, feet are well in front of his head, Fitch was 80% of the reason for this being a KO.
Same here with Kampmann.
Standing on one leg in the middle of wild swing, possible the worst base imaginabe. (Help me out, I don't know who this is)

Now if we compare to other situations:
GSP not in a particularly good position either, and not know for a godly chin survived an extended mauling by Hendricks through out the fight.
Koscheck.
Lawler hit clean twice, a good chin historically but remember what Woodley did to both Koscheck and Lawler (although Lawler fought Woodley a bit later, and the then situation was similar to the first 2 gifs of Hendricks)
