I'll answer your question for you - I may not know how a "real champion" shows sportsmanship but I (along with most of the Trojan faithful) know how to accept defeat with grace and class, for that is one of the things the MW program teaches. Having some friends and colleagues from Maryville, I can be sure I was one of the first to congratulate them on their win last year - even going to the visitors side immediately after the game to do so.

Sportsmanship is, in a basic sense, conforming to the rules of sport. More grandly it may be considered the ethos of sport. It is interesting that the motivation for sport is often an elusive element. However, it often emerges that skills are honed to increase performance and achievements in competition, rather than the converse.
Sportsmanship expresses an aspiration or ethos that the activity will be enjoyed for its own sake, with proper consideration for fairness and ethics and respect and fellowship for one's competitors.
Often the pressures of competition, individual achievement, or introduction of technology can seem to work against enjoyment by participants.
Poor sportsmanship is the converse of good sportsmanship.
Poor sportsmanship can either be the winners "rubbing salt in the wounds" of the losers.
Another example of poor sportsmanship failing to congratulate the winners.
