Amazing.

There are debates all over the internet, regarding how dominant he is as a historical sports figure. You are getting all the Jordan arguements, the Tiger Woods arguements, the many elements and nuances for them.

And as a fanboy of those guys, this dude is making a serious mark. And he isn't really even at his potential peak for the sport. The thing is, there just isn't that big of a fanbase for track and field. Plus it is only a few races here and there every year. So I can't see him ever getting the recognition he deserves. But I think he is easily one of the most dominant of all time. And if it continues, he will make records we won't see beaten for a very long time.
