Coughlin's contract had previously been scheduled to expire after the 2012 season, but the Giants were eager to reward the two-time Super Bowl winner with an extension.
"It has always been my belief that it is an honor and a privilege to be the head coach of the New York Giants," said Coughlin. "I'm thankful to John Mara and Steve Tisch and their families for their support and the recognition of what our players and coaches have accomplished. And I'm grateful for the working relationship Jerry Reese and I have. We've got a lot of work left to do."
"Tom is the right person in the right job at the right time," said chairman Steve Tisch. "I just really appreciate how our players respond to his leadership, and obviously our organization has benefitted tremendously because of the relationship Tom has with his players."
