I hired some movers once, these guys really 'hustled'; they moved quickly and worked efficiently. You can say this of a sports team as well. It is a colloquialism with good and bad connotations. Someone who has hustles can be seen as getting things done. The negative is a 'hustler' someone who gambles on games of skill pretending they're worse than they are to draw people in[1] ie crooks or con artists.
