When Tiger first came onto the national scene, the popular notion was that Earl pushed him very hard, and the press certainly ran with this, emphasizing in every story how Earl was a Green Beret. Later, it came out that Tiger was the one who begged his dad to take him to the course or the range all the time, and even Tiger has said that his dad was somewhat of a softie, it's his mom that instilled the killer instinct.
You may be right about the Wies, but me, I'll guess just the opposite. The media is doing what it always does, selling a story; the facts are almost immaterial.
