I think if you sit back and think about it, it's not a real good nickname for one of the most dominant sportsmen in history. I mean, look at Edward's nickname, it inspires thoughts of fury, wind and speed, and it's also relevant to him because of his Texan origins. Now look at "The Doctor" in comparison... a guy in a labcoat with a stethescope.... not really that cool IMO. I guess it could be a cultural thing, with Doctors being worshipped as demigods in Italy and all that, but I think he could have done much better.
