Well, his hand position when his recovery enters the water is pretty bad, or at least not very clean and high drag. When the thumbs stick way out to the side, that drives me nuts.... I have noticed that all of the elite swimmers tend to enter the water on their recover stroke, pretty close to the body center line. I figure this is that because the shoulders are still rotated, they are closer than they would/will be if the shoulders are parallel to the water. Looking at any swimmer on dry land, if the shoulders are square to you, and arms are extended, the arms are pretty close to 11 and 1 o'clock. But, if you rotate to that 40 to 45 degree angle and look at them straight on, the hands are much closer together. This swimmer does cross over a bit too far.

05:41 R u insisting he has to do I stroke instead of S stroke? or he has to pull his arm on side line of body instead of center line?
