A totally irrelevant question.
At the pinnacle of sport used to stand the world heavyweight boxing champion.
That was back in the Ali era and before - now it is the fastest man the world has ever seen and he has more personality in that woolly hat he discarded than those Klitschko brothers have had in a lifetime of victories in the ring - and sad to say, also that of Rudisha.
Had you been in the stadium on 100 final night, you would have seen the contrast.
Once Bolt entered the track, nobody could take their eyes off him, he is charismatic and mesmerising like no other athlete I have ever seen.
That is why over 2 billion people worldwide tuned into the 100 final that night.
Drop Bolt into any country in the world (possibly apart from the insular USA) and he would be instantly recognised and mobbed wherever he went.
Dominance? Bolt is Mr London 2012 Olympics himself - without his presence, the Games would have been like staging Hamlet without the Prince of Denmark in the cast.
