The Dallas Cowboys and the rest of league will no doubt mourn the loss of Dan Reeves.
Dan Reeves is best known as the head coach for three different NFL franchises and one of only ten coaches in league history to win 200 career games. Over an NFL tenure that spanned nearly four decades (in an official capacity), he was a member of the coaching staffs for an incredible nine of the first 33 Super Bowls.
But Reeves got his pro football start as a running back for the Dallas Cowboys, amassing 1,990 rushing yards and 25 touchdowns over the course of 100 games in an eight-year playing career.
