Why the Difference?

In team sports it's common courtesy to not run up the score on your opponent. In basketball and the NFL you put in the reserves, in baseball you throw in your young guys, and in all three you try to get the game over with as soon as possible. Two leagues, though don't like to go by this courtesy rule. The BCS and in all of soccer, coaches want you to run up the score. In every soccer league (UEFA or MLS) the way ties are broken up is by their goal difference. In the BCS, not only do you need to have a basically perfect season (which is another thing I have a problem with) but you also need to win by as much as possible. Now, I don't know about anyone else, but I don't feel this sends a good message to children. Is it an easy way to figure out a tie breaker? Sure but it's not the way any other sport does it. I feel the idea that you need to score as much possible just send the idea to kids that being completely aggressive and not have ANY compassion for the other team or anyone in their lives at all. Aggression can be good thing in sports but many people do take what they do on the sports field and use it in their lives. Kids don’t need reasons to be overly aggressive. I think the better thing would be for soccer and college football to conform to the tie breakers other sports do.
