Former Cowboys running back Ron Springs died Thursday of a heart attack. He was 54. Springs was in a coma after going into cardiac arrest in October 2007 during an operation to have a cyst removed from an elbow. The latter years of Springs' life were punctuated when his former Cowboys teammate and best friend Everson Walls donated his kidney to save his life. The two started a foundation that touched the lives of many, and they even wrote a book about their journey. Read more: http://sports.espn.go.com/dallas/nfl/news/story?id=6536754 54? That is young.
