A lot of folks would say how can anyone from Iowa have a meaningful conversation on, as you say, "black diversity," with only 3.7 percent of the state being black. ISU named their football stadium after their first black player, before it was a popular thing to do, 25 years ago. They've made a lot of hay with that over the years.
Is it meaningful? Depends on who you ask. As football programs go, there's only on major university in the state with a "diversity" PR problem, and it doesn't appear to be the clones.
