With the departure of offensive coordinator and quarterbacks coach Nick Quartaro at the end of the prior season, Ed Warinner returned from a two-season stint as University of Illinois's run-game coordinator and offensive line coach. He brought in a new, more aggressive, faster-paced, no-huddle offense. This was Warinner's third season with the Jayhawks since he had previously coached the offensive line and served as run-game coordinator in 2003–2004.
Bill Young (6th year) and Clint Bowen (7th year) were defensive coordinators. Tim Beck (3rd year) was the wide receivers coach and passing game coordinator.

This 45–13 win gave the Jayhawks a 3–1 record versus the Rockets and a 7–5 record versus opponents from the MAC.

Fox Sports reported, "It was only the second victory for Kansas in the last 39 games against Nebraska, which appears to be coming to pieces in the fourth season of embattled coach Bill Callahan."
The Kansas Jayhawks game against the Oklahoma State Cowboys attracted a great deal of attention. This was due to the match up between both potent offenses. The crucial match up was that between cornerback Aqib Talib and star Cowboy wideout Adarius Bowman. In the 2006 matchup between the two, Bowman had 13 catches for 300 yards. However Bowman left the game with an injury after the first half. In the first half, he was held to 22 yards on 4 cathces with no touchdowns. The game was broadcast to 63 percent of the nation on ABC as the top primetime college football game of the week.

On November 24 the Jayhawks met the Missouri Tigers at Arrowhead Stadium, in Kansas City, Missouri, in the final regular season game of the year. Known as the Border Showdown, this year's annual contest was the most significant in recent years as the winner would claim the Big 12 North Division title, advance to the Dr PepperBig 12 Championship Game in San Antonio, Texas, and likely claim the top spot in the BCS rankings and national polls with a win (No. 1 LSU lost 50-48 in triple overtime the previous day to Arkansas). The game received considerable media attention, and the ESPNCollege Gameday crew were at the game. It drew 80,537, the second-highest attendance in the 35-year history of Arrowhead Stadium. The Jayhawks entered the contest with an eleven-game winning streak since losing the final game of the 2006 season against their cross-border rivals in Columbia, Missouri, by a score of 42–17. But they would leave with their second straight loss versus the Tigers and a 6–6 series record since the formation of the Big 12 Conference.
