Lemieux's last fight was against Marcus Upshaw. He won an easy decision, but that fight showed how Lemieux hasn't progressed. He still fights the same way he did in his first fights: he rushes on the opponent and unleashes all his power. If the opponent doesn't fall, he is clueless, unless his opponent has no skills as well...
He has the power to knock out most fighters, but I just hope he will learn how to box one day, he is still young.
