The Kansas City Chiefs know that they're going to get the opposing team's best shot every time they step on the field. That comes with being the NFL's lone unbeaten team. They wouldn't want it any other way. "We love it," Chiefs quarterback Alex Smith said. "You want the stages to get bigger. That's why you put all the work in. You want this opportunity. You want that honor." The Chiefs got another stiff test from the Cleveland Browns on Sunday, racing out to a big first-half lead and then holding on through a harrowing second half. The result was a tenuous 23-17 victory and just the second 8-0 start in franchise history.
