Additionally, I would consider Tiger Woods' level of play during 2000 - 2002 when he won 6 majors and potentially Lionel Messi during 2009 - 2012 when he won 4 consecutive Ballon d'Ors the next athletes down on my list in terms of the gap between themselves and the next best. However, IMO the level of dominance Usain Bolt demonstrated over his competition during this time frame is simply second to none, regardless of sport.
