Killers in the box? Is this an idiom or something? What does it really mean? It's a soccer coach complimenting the offence of their team's rival. I didn't know its meaning could be so dependent on context. Could you also post some common usages in which the meanings are quite different from this one? Many thanks.

Tenses Greetings. I read the below sentence on the Atlantic(http://www.theatlantic.com/business/archive/2016/10/working-architectural-designer/505718/) and didn't understand why the present simple verb ''believe' was used in the clause after the past simple verb ''found''. It's against the grammar rule I have been taught. '' In a study earlier this year, the American Institute of Architects found that female architects largely believe that there isn’t gender equality in their industry, and cited familiar concerns about work-life balance, long hours, and inflexible schedules as reasons for the underrepresentation of women in the field.''

Pronunciation of ''English speaker'' I find it hard to pronounce this phrase smoothly. Do native speakers reduce the sound ''sh'' as in English in spoken English? Thanks in advance!
