Coaches expect their players to practice, not merely because the coach tells them to practice, but because practice is precisely the way in which players improve, honing their attributes and developing their skills.  Of course, the act of coaching demands its own set of attributes and skills.  If coaches are to improve as coaches, they too need to practice.  Being out in the field doesn’t cut it for the players and it doesn’t cut it for the coaches; both need a place to focus on professional development without the “distractions”  of the field.
