Day by day, Alzheimer's disease is robbing Edith Royal of her husband, Darrell. "He's in his childhood now," she said in an interview this week at the assisted living facility where they reside. "Sometimes, you wonder if anybody is ever going to make a breakthrough fighting this disease." She is doing what she can to help while also caring for the former Texas coach who won two national championships with the Longhorns in 1963 and 1969 and a share of a third in 1970 and is regarded as one of the giants in the game. The Royals hope Texas fans - and some from Oklahoma as well - will pitch in.
