Kickers have one damn job. Kick the ball through the uprights. To quote Bruce Lee: "I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times."
That's exactly what these kickers do. They kick the ball the exact same way every time. Of course, they have to adjust depending on weather and field conditions, but they still do the same kick repeatedly. These kickers are supposed to be the best in the world, and they've been flopping big time. Not sure where the underlying issue is.
