In this video, on the surface of it, it appears that Sheamus is using his superior strength and power to blast Daniel Bryan with a huge backbreaker, one which will likely lead to a painfully close near fall. In reality, if Bryan wasn't such a great athlete, the above scenario would never take place. Boiling it down a little, it's Bryan doing most of the work here. Not only does he backflip off the top rope, but he then needs the wherewithal to sprint off the ropes and guide his body into the perfect position for Sheamus to manipulate his movements and drop him across his thigh, looking for all the world like he's just spiked Bryan's spine with the point of his knee. The Tilt-A-Whirl Backbreaker looks impressive, but it's not something anybody could do to another without the other person working themselves in the right way. Physically impressive, but physically impossible.
