College football Saturdays this fall will find Dr. Brooks Keel wearing blue and cheering for his beloved Eagles as they shoot for a second straight Sun Belt title. A perfect union, however, of a personal and professional opportunity is calling Georgia Southern University’s president to Augusta, so while his rooting heart may remain True Blue, he will be cheering from about 80 miles north of Statesboro. The Board of Regents, which oversees Georgia’s university system, named Keel on Wednesday president of Georgia Regents University in Augusta.
