Sage Rosenfels is a Jewish American former professional football player.
Rosenfels (born March 6, 1978) was born to a Jewish father and a Christian mother in rural Iowa and was an all-around standout athlete in high school, lettering in football, basketball, baseball, tennis and track. After high school, he attended Iowa State University where he was a two-year starter and led the team to victory at the 2000 Insight.com bowl over the University of Pittsburgh.
In 2001, the Washington Redskins selected Rosenfels in the fourth round of the NFL Draft with the 109th overall pick. After spending one season riding Washington's bench, Rosenfels was traded to the Miami Dolphins and in 2006 he signed with the Houston Texans as an unrestricted free agent.
The Sporting News' February 2007 offseason awards issue predicted that Sage would be 2007's Tony Romo, the breakout quarterback of the year coming from a backup role. While he did manage to start five games and lead the Texans to a 4-1 record over those games, Quarterback Matt Schaub cemented himself as the team's QB of the future.
In 2009, the Texans sent Rosenfels to the Minnesota Vikings where he ended up remaining a backup to quarterbacks Brett Favre and Tarvaris Jackson. The Vikings proceeded to trade Rosenfels to the New York Giants in September 2010 where he remained a backup, this time to Eli Manning.
After being released by the Giants on October 4, 2011, the Miami Dolphins signed Rosenfels but released him less than six months later. He was claimed off waivers by the Minnesota Vikings in December 2011 but was released in August 2012.
