In his new book "Acing Depression: A Tennis Champion’s Toughest Match," 1970s standout Cliff Richey admits that that his frequent on court tantrums served as a mask for clinical depression. The former U.S. Davis Cup hero, who was nicknamed

“The Bull,” said that there were days when he would place black trash bags over the windows of his house, stay in bed all day and cry.
