Wrap-up: Chiefs 31, 49ers 10

What it means: The Kansas City Chiefs are 3-0. This team won a total of 10 games the past three seasons. After winning two tough games to start the seasons, Kansas City absolutely dominated San Francisco, 31-10.

Tomorrow's Talker: Matt Cassel caught fire in the second half. After struggling in the first two games of the season, many Chiefs fans were complaining about Cassel despite the 2-0 record. He started slow Sunday, but he had a fine second half as the Chiefs turned a 10-3 lead at halftime into a laugher. Cassel completed 16 of 27 passes for 250 yards. He threw three touchdown passes and was intercepted once. If Cassel can continue this type of production, the Chiefs will be hard to beat, especially with running backs Jamaal Charles and Thomas Jones running as they did Sunday.

Big Revelation: This defense is good. Kansas City has allowed 38 points in three games. Once again, the run defense was terrific. New defensive coordinator Romeo Crennel is doing a terrific job.

What’s next: Kansas City has its bye and then it enters its toughest stretch of the season when it visits Indianapolis and Houston.
