The coach's leadership has been identified as a critical determinant of team achievement, individual athletic performance, and athlete's satisfaction. The earliest research in leadership focused on attempts to identify qualities or personal attributes of leaders which were associated with positive outcomes. Students who proved to be the leaders in the group on intellectual task also tended to be leaders on the clerical task, but not the mechanical. This suggests that traits alone to not explain leader effectiveness. It seems to me that these are all the requirements that you would need to be a coach.
Failure is attributed to a lack of effort and seen as a part of the learning process.
This could lead to increased effort and using positive learning strategies - all things a good coach should know and remember. When goals are set, especially performance goals, others tend to evaluate you in relation to each other and each goal. This did not surprise me because I've played basketball most of my life. I also believe that if you perform well, you will be successful. When I hit most of my three-point shots, I feel much more successful that when I only hit one out of seven shots.
