"Oh my god, finally! This is what an arm swing is supposed to look like. I don't even care about breaking down the whole sprint right now. From a dead stop, he throws his arms with violence, but it's still controlled. His head stays neutral, he gets real triple extension, and the first step has genuine purpose. That is how you start creating power from a static position. Also, watch it again and look at his teammate in the background. Just absolutely cheesing. Love it."
