Answer:
To have good sportsmanship is to have respect for the winning team, whether it be your team or the opposing/rival team.
Explanation:
Good sportsmanship is a quality of a person in having the grace and understanding of having respect for the other team even in circumstances that do not favor them. In short, it means to treat others with respect even when one lost a game.
So, when someone says "to have good sportsmanship", it basically means to be graceful about having the courage to accept any outcome of a game with respect. This quality is for everyone, be it the players, the spectators, the coaches, or even parents. Admitting defeat, accepting it with grace, and respectfully treating the winning team with good grace is all part of being a good sportsman.
