Just viewed the entire fight on Youtube. What a performance! It reminded of me of Joe Calzaghe's complete domination of Jeff Lacy. Albeit not as dramatic, but complete in his domination against a world-class killer in Gassiev. Usyk gave a dominate complete performance of the sweet science. At times he made Gassiev look like an amateur. If he can maintain his boxing skills and stamina in the heavyweight division. A lot of Heavyweights are doomed, namely Joshua and Wilder. Sensational performance! I forgot how rangy and smart Usyk is. Congrats!!!
