He did not play in his rookie season of 2003, spending the year on the Patriots' injured reserve with an arm injury.
He was waived by the Patriots on September 6, 2004 and was signed by the New Orleans Saints to the team's practice squad, where he spent the entire 2004 season.
Kingsbury was drawn to Houston through his ties with Dana Holgorsen who had been the offensive coordinator at Texas Tech prior to Houston.
Kingsbury was also an Academic All-Big 12 Conference choice following his sophomore campaign in 2000.
Kingsbury, 6' 3", 213 lbs, was selected by the New England Patriots with the 201st overall selection (6th round) of the 2003 NFL Draft.
With Holgerson departing to become the offensive coordinator at Oklahoma State University, Kingsbury was promoted to the position of co-offensive coordinator and quarterbacks coach for the Cougars serving alongside former UH receiver Jason Phillips.
Kingsbury quickly gained Coach Kevin Sumlin's trust and began calling all the offensive plays & was recognized as the 2011 Offensive Coordinator of the year after Houston led college football, averaging 50 points and nearly 600 yards of offense per game.
