As your are admiring corners, here is one from today
Nice GIF, Before He swings there is a guy in the stands whose face is hidden by His hands(hat,sunglasses). Use this a reference...
The rear knee starts pulling the rear hip rear hip, as that happens look at His hands. They seem to float for a split second. That's the hands setting up a barrel move behind the corner. Now look at the barrel during this same time frame. It swirls around above His head from front to back. So, even though the hands seemed to be floating they were actually working the barrel.
Now comes the best part, Look at the path the barrel takes behind Him. Remember the guy in the stands where His hands started? Watch the barrel cut that guy in half. See the speed of the barrel way back there? Now look again at his hips and feel how they are in front of this action pulling the hands through.... Do you see it? Can you feel it? That's the corner. IMO
