@Guivre: Uh... how would a coach be physically reprimand their players? I always feel it's the parents' responsibility to discipline the child so I wouldn't want someone else touching them.

Also, why would a coach have to "physically reprimand" their team? I mean, you shouldn't be physically punishing someone for playing poorly. And if they had a tantrum or something they should kick them out of the game and maybe have a parent take them home.
