ST. JOSEPH, Mo. (AP) – Give credit to Chiefs coach Todd Haley: He’s sticking with his plan.    It was hard to give anybody else in camp much credit after Friday night.  The team was back to work at its preseason headquarters on the campus of Missouri Western State University on Sunday, still smarting from a 25-0 thumping at the hands of the Tampa Bay Buccaneers. It was the kind of home rout that might typically cause coaches indigestion, but this season has been anything but typical.  “You have to, as a head coach, look at the big picture all the time,” Haley said in a measured tone. “It’s a different set of circumstances, and the goal is to be ready for Sept. 11, and that’s all that I’m focused on.”
