The Giants wanted to bring in an established coach who could bring discipline back to the Giants, which lead to the team hiring Tom Coughlin on January 6, 2004.
Coughlin had been with the Jacksonville Jaguars and had made them a contender for several years in the AFC, but he was fired after the 2002 season and took a year off in 2003.
In Coughlin's first season, the team started out 5-4, and he decided to bench Kurt Warner for their first-round draft pick Eli Manning. The Giants finished 1-6 and ended up with a 6-10 record.
Since then, Coughlin has not had a losing season with the Giants.
They went 11-5 in 2005 and 8-8 in 2006 and made the playoffs, but were eliminated in the first round both times.
Coughlin was nearly fired after the 2006 season and had to tell John Mara why he should keep his job for 2007. Coughlin saved his job, and although they started out 0-2 in 2007, the Giants finished 10-6 and made the postseason.
The Giants went on their first magical run in the playoffs. They knocked off the Buccaneers, Cowboys and Packers in the NFC playoffs, and then shocked the world by beating the 18-0 Patriots in Super Bowl XLII to win the Giants third Super Bowl.
Coughlin was off the hot seat and got an extension from the team as a reward. They went 12-4 in 2008, but were eliminated in the second round by the Eagles in the playoffs.
The Giants went 8-8 in 2009 and 10-6 in 2010 and failed to reach the playoffs again and some started questioning if Coughlin was the right guy for the job again.
In 2011, the Giants dropped to 6-6 and people were ready to fire Coughlin again, but the Giants finished 9-7, won the NFC East and ran through the Falcons, Packers and 49ers in the NFC playoffs. They upset the world again by beating the Patriots in Super Bowl XLVI, the team's fourth Super Bowl.
In a span of four years, the Giants had won two Super Bowls under Coughlin, which has now lead to Coughlin having job security for the rest of his tenure as the coach.
He's survived the hot seat twice and responded with Super Bowls each time.
In the eight years with the Giants, Coughlin has done one of the best coaching jobs in team history, and he's not done yet.
