When they started their youth league here locally, the mandated coaches go thru a training program for their coaches. I was given a few minutes to explain rules. I always covered what is holding and what is not holding. I have always tended to take @JustRules philosophy I tend to focus on the feet, when you get beat, you have to let go. It helped things tremendously with coaches understanding the point that two 6th graders hugging it out isn't holding.
On a side note, after reading all the stuff that goes into the decision making process for a holding call, I kinda got to thinking, wow, I process all that information in a fraction of a second, and I'm reaching for my flag or letting it go..................Man I really am good! 😁
