Gary Haskew, known to Tennessee Valley sports fans as "Dr. Basketball" on the long-running WGOW 102.3 afternoon show "Sport Talk" has died at the age of 74. Haskew's brother and former co-host Jerre said Gary died of a massive heart attack on Monday afternoon. On his Facebook page, Jerre posted, "Please pray for our family. My beloved Brother Gary just passed away. God rest his sweet soul." Haskew's friend Kenny Smith said he had experienced health problems a few years ago, but had been doing well recently, and his sudden death came as a sad surprise. "He's the kind of guy who can't be replaced," Smith said. "He made people smile everywhere he went."
