Don't know how being apart of PWI conference means a HBCU is now a "white" HBCU is beyond me. Hampton, NC A&T State, and Tennessee State (who supporters fought over 10 years in federal court against the state of Tennessee and won) are still holding true their founding values and all have a majority black student student population and faculty\staff. What Tennessee State has done in a very hostile environment is great and have use the increase in travel costs to their advantage with the OVC and Big South Alliance. I can see in the near future that all of their out of conference games could be against HBCUs (except for one game against an FBS school).
As far as Grambling State playing Ohio State, it is a good move if they manage to hold their own and they can actually clear a profit from the trip.
