Thanks for the list Ralph. I'm going to add it to my collection of soccer stuff.
I would like to add 'coaching flexibility' to the list. To many times I'm seen a coach/trainer walk into practice and do everything possible to force their practice plan through. Children can be emotional, fickle and stubborn, and coach must be able to read the situation and adjust the practive accordingly. Coaches must also be able to recognize when a practice needs to be slowed or accelerated based on the response of the players.
