Charles Haley never was fond of the media, especially when stories about his infamously volatile temper dominated the news during his playing days in San Francisco and Dallas. But his views have changed. The retired linebacker/defensive end is on a media tour promoting his new book, Fear No Evil: Tackling Quarterbacks and Demons On My Way to The Hall of Fame, and he has a lot of truths to share. Back in 2002, three years removed from his last season, Haley was diagnosed with bipolar disorder. After years of being in denial about his illness, he’s now working as an advocate for mental health.
