Mason Walker Crosby (born September 3, 1984 in Lubbock, Texas), is a professional American football placekicker for the Green Bay Packers in the National Football League. During his playing days at the University of Colorado, Crosby was widely considered the best kicker in college football, as evidenced by ESPN draft expert Mel Kiper Jr.'s Top 5 Seniors by position in 2006. Crosby was a unanimous selection as a First Team All American by the Associated Press, the Football Writers Association of America, The Sporting News, and Walter Camp Football Foundation for the 2005 NCAA Division I-A football season. He was the runner-up for the Lou Groza Award, despite being heavily favored to win.
During his senior season at Colorado, Crosby became the first player in Big 12 Conference history to be named player of the week eight times. In late 2006, he also became Colorado's all-time leading scorer, with 308 career points. The previous record holder was Eric Bieniemy (1987–1990) with 254.
While enrolled at Colorado, Crosby displayed extraordinary leg strength, making a school record 60-yard field goal against Iowa State in 2004. Crosby’s 58-yard field goal against Miami in 2005 was the longest ever kicked in NCAA Division I-A football at sea-level without a tee. In all, Crosby holds 31 school records. Crosby connected on 66 of 88 field goals in total during his college career, and 30 of 34 inside 40 yards.
