FORT WORTH, Texas Robert Griffin III looks forward to sitting down and talking with NFL executives and coaches during the NFL combine.

While Griffin set plenty of records with big numbers while becoming Baylor's first Heisman Trophy winner, he said he's excited about explaining the offense to pro teams. He said it's not as simple as many people made the potent high-scoring spread offense to be and is based on many pro principles.

Griffin accepted the Davey O'Brien Award as the nation's top quarterback Monday. He said he will run the 40-yard dash and do some of the drills at the combine.

He likely won't throw in Indianapolis this week, and instead save that for his pro day March 21, which he moved up a day to avoid going the same day as Andrew Luck's pro day.

The Chiefs agreed to terms on a $19.6 million, three-year deal with cornerback Stanford Routt, which should help Kansas City absorb the potential loss of Brandon Carr.

Routt is owed $5 million next month from Oakland, which released him after the first year of a $54.4 million, five-year deal. The $11 million he will make in 2012 puts him among the NFL's three highest-paid cornerbacks.

Boxing

Chisora takes blame: Dereck Chisora apologized "wholeheartedly" for the brawl with David Haye that followed his loss to WBC heavyweight champion Vitali Klitschko on Saturday night.

Haye blamed Chisora for the clash that followed his fellow Londoner's defeat in Munich and the beaten challenger has acknowledged the violence at the post-bout news conference marred the biggest night of his career.

"Whilst my behavior was inexcusable, there were many things that went on behind the scenes that ultimately caused my frustrations to boil over," Chisora said. "Despite all of this, the bottom line is I have let my family, my team and - worst of all - the sport I love down."

Chisora, who was questioned for seven hours by German police and is being investigated by the British Boxing Board of Control over the incident, did not say what provoked him to descend from the top table and confront Haye.
