We all are well-aware that an MBA from U-Chicago is nearly always a springboard and gateway to a career as a traveling salesman, and also Elgin is a virtual enclave for U-Chicago biz-grads.
Also, many of the great business leaders of our generation (Jobs, Bezos, Gates, etc.) in times of strategic need will always seek both strategic and tactical guidance from one of their thousand internal salesmen. Duh. Clearly they would not seek input from the guy running biz-dev or corp-dev, but a sales guy really has the pulse of the ever-changing dynamics and competitive landscape within a given vertical sector. This is known.
