While promoting his album to the NY Post, Bolt had some interesting things to say about Sha'Carri Richardson. Here are some of the quotes.
“I would tell Sha’Carri to train harder and to be focused and not say too much … If you talk that big talk you have to back it up.... Jamaicans were vexed because she was talking a lot of s–t before the actual race, it is just one of those things. Jamaicans don’t like when people talk s–t about us because we are a very proud people. So if you talk about us we are gonna want you to back it up. It definitely gave those women the extra push [to win.]”
