Buddy Teevens, the innovative coach who brought robotic tackling dummies to Dartmouth practices, has died of injuries he sustained from a bicycle crash in March. He was 66. Teevens was a former star Dartmouth quarterback who went on to become the school’s all-time wins leader with a 117-101-2 record in 23 seasons. He coached the Big Green from 1987-91 and returned in 2005. His teams have won or shared five Ivy League championships. Teevens’ lasting legacy will be in his efforts to make the sport safer. He reduced full-contact practices by focusing on technique, while still leading winning teams. He also led the development by Dartmouth’s engineering school of the the Mobile Virtual Player, a robotic tackling dummy that has also been used by other college programs and NFL teams.
