There is the kind of dad who is stable and consistent, who provides for his family, who wouldn't dream of abandoning or abusing his family—but who never says "I love you."

Bo Jackson is still the only man to be an All-Star player in both baseball and football. Some argue that he is the greatest athlete in history. Maybe so. But that didn't make up for his relationship with his father—or lack of it:

My father has never seen me play a football or baseball game. Not a single one. Can you imagine? Here I am, Bo Jackson, one of the so-called premier athletes in the country, and after the game I'm sitting in the locker room and envying every one of my teammates whose dad would come in and talk, have a drink with them after the game. I never experienced that.
