I thought it was Willie who had the MBA and took the thing large
Si is the only adult Robertson on the show who does not have a college degree, including the wives. I do believe Willie has been the CEO and took the brand large since Phil retired. Phil has referred to Willie on the show as the "guy that deals with the money."
Phil attended Louisiana Tech University where he played football, but turned down an opportunity to play professionally with the Washington Redskins. He received a master’s degree in education and spent several years teaching.
