Under construction. Nishioka Sensei states that coaching's emphasis are essentially on winning. He contrasts the coach's role with that of the sensei where he believes the emphasis is more on instructing. Typically coaching requires more time with fewer individuals. He further elaborates that when instructing the sensei is usually hard pressed to yell at his/her students in front of others. He implies that the role of the coach is more "parental" and may be prone to provide strong feedback to a player regardless of who is around. He also states that a coach may take a position with a player that may be unjustly enriched with an unwarranted -- one which the coach may not be inclined to see corrected where a sensei would disagree with such a result. In other words, the sensei may be more likely to correct an improper result.
