I still think Bolt should have gone for the 400 world record (as Michael Johnson suggested) to become the only man ever to own all three sprint world records. Wouldn't that have been more impressive than another 100, 200 gold? (Which may not even happen) Unfortunately it is too late now for him to get the 400 record as he is probably too old to get it. What do you folks think would have left a bigger legacy for him?
