the thing that Noah has which none of the other have is the charisma. Like Bolt, hes seen dancing around after his victories, hes confident but not too arrogant, hes charming on camera, and is personable and open in interviews. Not to mention hes dumb fast at his age and can handle pressure.
The only other athlete who really comes close in terms of all those qualities is Sydney, but youre much less likely to see her dancing around after races and hyping up the crowd. Its probably because she runs the 400m and 400m hurdles, two races which tire you out far more then the 100m and 200m Noah runs.
