If he is an 8u coach I would guess he doesn't have too much experience coaching softball or youngsters. One of the worst things at a practice is players standing around. We do a lot of station work and spend very little time with the whole team at any one thing other than if we are doing infield situations. Does he have assistant coaches or parents willing to help out? If I were you I would approach him and ask if he needs help to make practices more efficient. Hopefully he will be receptive to a conversation and use it to his advantage other than an insult to his coaching abilities. I am not a huge ego guy and take suggestions regularly. I also use this board for a lot of suggestions so all you coaches keep posting your experiences.
