How is it a myth? Sure, you have to put context to it. LaRue was at the 17th or 18th hole of his career and it was the last in a long line of concussions, but that was the incident that literally ended his career. He never appeared in a game again. You can try to rationalize it all you want, but that's what happened. Not to mention kicking a dude in the head with your spikes is worse than throwing a shoulder into a guy.
