Former World Heavyweight Champion Deontay Wilder (42-2-1, 41 KOs) revealed that his toughest sparring partner was Alonzo Butler (34-3-2, 25 KOs).
It should be noted that Deontay chose Butler despite the fact that he sparred with world champions Wladimir Klitschko and David Haye.
“I had a really good, solid war with Alonzo Butler, the Big Zo. He is the fastest heavyweight I have ever seen. And this is despite his size - he weighed more than 113 kilograms, but he could move.
If he had better managers and promoters, then he could become the heavyweight champion of the world. When I just got up and saw him, I was very impressed. I looked at him and thought: "I want to become the same." Alonzo was a tough guy and the first fighter whose body shot I felt. In those days, I learned a lot from him,” Wilder said in an interview with TalkSPORT.
