One assumes to get to the next level that he has to have the intellect (brains) to achieve that....

As we know, many of these riders have the ability and not the brains.... Some can overcome that by their ability regardless (PVal) comes to mind...
That said, if one does not have the brains or the desire than they will never get to the level of Bailey, Johnny V., Pincay, R. Baze out here. Then again, we are talking about the cream of the crop - Hall of Famers...
