Data from WFU Fact Book
Right. I'll make the point again that Allman is the Dean of Admissions, iow the school's VP of Sales. She is not the CEO or the VP of Product Development. WFU appears to have had a fairly flat level of appeal to black students over the past 15 years. I guess you could try to spin it differently and blame her, but the point remains that there's only so much she can affect, regardless of some picture she was in almost four decades ago.
