I think "" implies "". I don’t know a dogfight system though, I guess the word comes from them. In a combat sport like boxing, it is not uncommon that a match-maker chooses the opponent which their boxer definitely wins in order to get his boxer confidence.

It is very similar to ”underdog” in English though, while the underdog is used when a team always lost regardless of making an effort, himself often doesn't intend to win from the beginning.

Sometimes makes an upset in a boxing match. Say, a match-maker prepares a world championship between ex-champion which seems already passed his best time and an undefeated-prospect for the future champion. An ex-champion seemed by a matchmaker though, he showed his pride and won the match. So, has a broader usage.
