Grossman then started for the Bears in their only post-season game. Overall, the Bears had a record of 10–5 in games that Orton started, including an eight-game winning streak after a 1–3 start.Despite the team's success, Orton finished with the lowest quarterback rating in the NFL (59.7) among all "qualified" quarterbacks (those with 224 pass attempts).Kyle Raymond Orton (born November 14, 1982) is a former American football quarterback.He played college football for Purdue, where he started four straight bowl games.He was drafted by the Chicago Bears in the fourth round of the 2005 NFL Draft.After an injury to Bears starter Rex Grossman, Orton was pressed into service as the starting quarterback during his rookie year, starting the first 14 games of the 2005 season, but was replaced by Grossman for the playoffs that year.In 2004, Orton was the preseason third-team All-American quarterback, behind USC's Matt Leinart and Oklahoma's Jason White.Orton had a nice start to the season, having led Purdue to a 5–0 start with 18 touchdowns and no interceptions.
The coaching staff asked Orton to minimize mistakes and to let the rushing attack and the defense win ballgames rather than employing an aggressive passing attack.
Orton was drafted by the Chicago Bears in the fourth round of the 2005 NFL Draft.
In the 2005 NFL season, he was rushed into the Bears starting lineup as a rookie after a preseason injury to starter Rex Grossman, and the poor play of back-up Chad Hutchinson.
In the offseason of that year, he was traded to the Denver Broncos.
Orton started his Broncos career by winning his first six games in the 2009 season, but injuries hobbled him in the second half of the season.
Following several weeks on the bench, in which he did not take a snap for the Broncos, he was released by the Broncos on November 22, and claimed off of waivers by the Kansas City Chiefs the next day.
