Don't be late Pedro said:So why is Bolt a special case then?
Because, if you look at his body, then you can see he has the potential there. I think we all agree that kenny's body is not a natural advantage over the other sprint cyclits as Bolt's can be for 100m. Most of us are actually surprised by how skinny he looks for a Sprint specialist.
Also relevant, Bolt is a showman that only really cares about delivering when the world is watching, so he'll mostly work for the world/olympics events.
