Deb Ploetz, wife of former Longhorn football player Greg Ploetz, had long said she didn't want to sue the NCAA for the trauma her husband suffered after playing football."Greg chose to play football," she told The Dallas Morning News in 2014, "so I don't really hold people liable for the choice he made."But eight months after her husband died at age 66, Deb Ploetz has changed her mind.
