Willie Roaf supposedly surprised the Kansas City Chiefs by retiring on the day players reported to camp, but the 11-time Pro Bowl lineman said he informed the Chiefs of his plans in May. "If I felt I could play like I used to play, I'd play again," said Roaf, a left offensive tackle. "I started running around and my legs were bothering me. I kind of knew right then that I would need to do this. I'm 36. I have to face that fact." New coach Herman Edwards is still hoping for an about-face.
