NFL: Chiefs coach Haley shows how far he's come

KANSAS CITY, Mo. — The victory was just icing. The progress could be seen long before Matt Cassel shook off a critical fumble and began the process of rehabilitating his image.

The progress started with Kansas City's rookie head coach, Todd Haley, who may have finally figured out what to do with his game-day emotions.

Rather than castigate his players, F-bomb his assistants and bicker with the refs, Haley spent his most productive Sunday as an NFL head coach fueling his players with positive energy. They responded with their most promising performance in two years.

Kansas City 27, Pittsburgh 24 in OT!

Yes, the Kansas City Chiefs, winners of five of their last 30 games, knocked off the defending Super Bowl champions at Arrowhead Stadium.

It wasn't a fluke. The Steelers tried to win the game. They didn't stumble into Arrowhead hung over from a night of being denied entrance into P&L nightclubs. The Chiefs played a good football game and took advantage of the Steelers' errors.

Jamaal Charles returned the opening kickoff for a touchdown. Tamba Hali led a Kansas City pass rush that harassed Big Ben Roethlisberger and eventually sidelined him with a knee to the head. Brandon Flowers manufactured the first of four Pittsburgh turnovers, poking the ball out of the arm of receiver Mike Wallace. KC safeties Mike Brown and Jon McGraw accepted the challenge of being physical against Pittsburgh's running game. Linebacker Andy Studebaker intercepted Big Ben twice, returning one 94 yards, setting up a Kansas City field goal.

And, most important, the Chiefs' $63 million acquisition, Cassel, showed some real courage down the stretch. I thought he was going to fold after his inexcusable 360-spin, I'm-afraid-of-a-pass-rush fumble that basically handed the Steelers a 24-17 advantage in the fourth quarter.

Cassel had been dreadful to that point, completing eight of 18 passes for 95 yards through a little more than three quarters of play.

"He was really down when he turned the ball over, but he bounced back and made some great plays," Haley said of his quarterback.

Cassel may have saved his Kansas City career. He certainly bought himself some time.

On KC's next possession, facing third and 9 from the Chiefs' 10, Cassel laced a strike down the middle of the Pittsburgh defense to Lance Long for 30 yards. Cassel followed it up with a 47-yard bomb to Chris Chambers. Cassel drove the Chiefs 91 yards in eight plays, hitting Charles with a 2-yard TD pass.

In overtime, Cassel set up the Chiefs' game-winning field goal with a 61-yard, third-and-5 connection to Chambers.
