Jake Plummer signed with the Denver Broncos in 2003 and replaced Brian Griese as the starter. In his first season with the Broncos, Plummer had his best season statistically. Plummer led the Broncos to the AFC Wild Card game where they lost 41-10 by the Indianapolis Colts.
In 2004 Plummer led Denver to a 10-6 record and in 2005 the Broncos went 13-3 and hosted the AFC Championship game, losing to the Pittsburgh Steelers 34-17.
However in 2006, the Broncos drafted Jay Cutler, a big armed quarterback out of Vanderbilt. When Plummer struggled, throwing only 11 touchdowns and 12 interceptions, the grumbling began to put in the stronger armed Cutler.
Head Coach Mike Shanahan would eventually bench Plummer in week 11 following two straight losses.
Under Cutler, the Broncos finished the season limping to a 9-7 record. Cutler would be named the starter in 2007 and Plummer was traded to Tampa Bay where he would choose to retire instead.
Cutler would end up going 17-20 as a starter in Denver and would eventually be traded to the Chicago Bears in 2009.
