I don’t see how the coaches were at fault.
And if they are found to be at fault then all sports should be outlawed, because the description of what happened is the description of every single workout for every major sport both male and female on the college level, as well as the high school level, and worst on a professional level.
I didn’t read the entire article, but although the coaches might not have any criminal culpability, they could still be in hot water (with the NCAA) for simply being present at off-season workouts.
There are supposed to be NO coaches present—all off-season workouts are (nudge, wink) ‘voluntary’.
