They have been working on this one for several weeks.
The coach is getting near his whit's end. So he demonstrates for the 967th time. Slide left, slide right, left knee up.
Ummmm, nope. The funny thing is several of the kids fall down when they try to do this, because they turn around to see the coach and lose their balance.
This is why I am not a soccer coach now ( I coached in high school, back when I had a little thing called "patience") I would be saying something like.... This isn't rocket science people! Slide, slide, leg up!
