NEW YORK: Tom Coughlin resigned as head coach of the New York Giants on Monday, saying he took responsibility for the National Football League team’s third straight losing season. The 69-year-old met with Giants co-owners Steve Tisch and John Mara on Monday afternoon, and informed them that he is stepping down after the Giants failed to reach the postseason for the fourth year in a row and the sixth time in seven years. The Giants have just two wins since October and capped their season with a 35-30 loss to Philadelphia. Coughlin, who served 12 seasons as head coach, was part of three Super Bowl championships, two of which came in a span of five years. He also spent three years as an assistant coach to Bill Parcells.
