Better translation for "underdog"?
Mined from an opinion post (http://blog.sciencenet.cn/blog-39731-510338.html):


劣勢者
弱勢者
新[入/行/進]者
後來者


I personally prefer the first one as the best translation; 弱勢 is a bit broader in meaning as it can mean weak in general rather than in comparison to something. The other ones just mean newcomer, so the disadvantage of being an underdog is only implied rather than explicitly stated.

You may also want to check out 弱旅 (opposite: 勁旅).
