Five years after coming out publicly, former football player Michael Sam recently spoke at Arizona State University on "Masculinity, identity and moving forward: I am Michael Sam."

Sam spoke with Global Sports Institute director of research Dr. Scott Brooks, who was at Missouri as a professor at the same time Sam played football for the school. Missouri is a conservative atmosphere on campus and in the town, yet Sam said he felt comfortable coming out there because of head coach Gary Pinkel. "He was a huge, huge factor in that," Sam said.
