It is player error on the rolls I've seen. Simply someone trying to do too much, the result is an injury since their body gets pushed that little bit more off balanced than it should. As for how I rolled mine, I've done it in tennis and a few times playing street football BAREFOOT... Instead of landing like this: | where my foot lands flat or almost flat, I land like this: / on the edge of my foot or shoe. When that happens as I said it really doesn't matter what your in, your turning your ankle. And I have used minimalists and much prefer traditional shoes for any running (distance/sprints) and will not use them in tennis because the chance of a injury, be it long term or immediate, is more likely.
