New England Patriots Koppen entered the
2003 NFL draft following college and was selected by the
New England Patriots in the fifth round with the 164th overall selection. Koppen entered the
2003 season as the backup to
Pro Bowl center
Damien Woody; however, when Woody missed Week 2 with an injury, Koppen was given the opportunity to start his first NFL game for the Patriots. Woody returned the next week. But, following a season-ending injury to starting guard
Mike Compton, the Patriots moved Woody to
offensive guard and Koppen started the remainder of the 2003 season at center, including in the Patriots'
Super Bowl XXXVIII win over the
Carolina Panthers. Following the season, Woody signed with the
Detroit Lions, leaving Koppen as the Patriots' starting center. Koppen started all 16 games for the Patriots in
2004, where he was a member of the Patriots' 2004
Super Bowl-winning team, in which the Patriots defeated the
Philadelphia Eagles in
Super Bowl XXXIX on February 6, 2005. After starting the first nine games in the
2005 season, Koppen was derailed by a shoulder injury he sustained in a November 13 game against the
Miami Dolphins. He was placed on injured reserve following the game. In the
2006 season, however, Koppen returned to his role as the Patriots' starting center. On October 12, 2006, the Patriots announced they had signed Koppen to a five-year,
$20 million contract extension. Koppen finished the 2006 season starting each of the Patriots' 16 regular season games. In the 2006 season, Koppen allowed only two sacks and committing only two penalties for the entire season. In
2007, Koppen missed one game due to a foot injury, but started the other 15 games. For the 2007 season, he did not allow a single sack and helped lead the Patriots to the only perfect 16–0 season in NFL history. The following season, in
2008, Koppen was selected as a starter in the
2008 Pro Bowl, his first appearance in the game. In both the
2009 and
2010 season, Koppen started all 16 games for each season. In the 2009 season, he was a member of an offensive line that allowed the fewest sacks (18) by a Patriots offensive line since the NFL's 1978 move to a 16-game schedule. In August 2007, Patriots head coach
Bill Belichick said the following of Koppen: Koppen was named to the Patriots' All-Decade team for 2000s in 2010. In 2010, Koppen also again started all 16 games for the Patriots. In a Week 1 matchup in the
2011 season against the
Miami Dolphins, Koppen fractured his ankle. On September 21, he was placed on injured reserve. Koppen was released on August 31, 2012, during the Patriots' final roster cuts prior to the
2012 season. For eight of
Tom Brady's 20 years as Patriots' quarterback, Koppen was the Patriots' offensive center responsible for snapping him the ball.
Denver Broncos Two weeks after being released by the Patriots, on September 10, 2012, Koppen agreed to a one-year deal with the
Denver Broncos. On July 28, 2013, Koppen suffered a torn
ACL during training camp and missed the entire
2013 season. He announced his retirement from the NFL following the 2013 season.
NFL legacy In addition to being a member of two
Super Bowl-winning teams with the New England Patriots and being named to the
Pro Bowl in 2007, Koppen is believed to be the only NFL offensive center ever to have snapped to two of the most successful quarterbacks in NFL history,
Tom Brady, during Koppen's 2003 to 2011 career with the Patriots, and
Peyton Manning, during Koppen's career with the Broncos in 2012 and 2013. ==Post-NFL career==
