re: What would Usain Bolt's 40 yard dash time be?

There is so much ignorance being posted here, I need to set the record straight about a few things.
1) Bolt is not a slow starter. When he set the world record at the 2009 World Championships, he led from gun to finish.


This chart show how Bolt's 10-meter splits compares to other great 100 meter sprinters.


2) With a PR of 10.34, Bo Jackson was not even in the same class as Trindon Holliday, not to mention Usain Bolt.

3) In Beijing 2008, Richard Thompson led through 30 meters and he was second through 30 meters in Berlin 2009. However, even in his senior year at LSU when he was both the indoor and outdoor champion, he always trailed Trindon Holliday in the early part of races despite going through the college season undefeated.
