John has been able to stay healthy (for the most part) and dominate WWE for 17 years, which is unheard of, and nearly impossible. For that reason, He will go down in history as the most consistent, and the Greatest WWE Superstar of all-time. Happy belated birthday, John. You earned my respect the first time we locked horns."
