I came across an article by Brett & Kate McKay and couldn't agree more with his words that：
A good sport stars must have good sportsmanship,and good sportsmanship encompasses many aspects of a man’s character, the most fundamental being respect. The good sportsman respects both his teammates and his opponents as equals. He plays with integrity. A win that does not come fairly holds no satisfaction for him. He is honest in his dealings with opponents, because he treats them the way he wants to be treated. He is unselfish in his desire to see all his teammates participate and enjoy the game. He is humble in his victories, and has the proper perspective on his losses.
In short, the qualities that go in to making a good man are the same ones that contribute to being a great sportsman.
