The United States goes into halftime down 2-0 to Colombia. The second goal came on a penalty, which was awarded after DeAndre Yedlin was called for a handball. Yedlin was turning away, but left his arm up. You can argue it was harsh. You can argue that this is almost always called. But it's pretty hard to argue that it didn't hit his hand.
It might be tempting to view this as it hitting his shoulder -- and I'll admit I was pretty convinced of this -- but upon closer inspection you can see that Yedlin's arm snaps back. The arm simply doesn't move like that if it's not hit by the ball.
