Former champions Jack Dempsey, Joe Louis, Floyd Patterson and Gene Tunney, as well as contender George Chuvalo all declared they considered the fight to be a fake. Some felt the knockdown was real but the knockout was fake. Ali biographer Wilfrid Sheed wrote, in his Muhammad Ali: A Portrait in Words and Photographs, that Liston planned to throw the fight for reasons unknown and used the legitimate first-round knockdown for that end. Sheed says that the punch and the knockdown "may have been genuine, but when referee Joe Walcott blew the count and gave him all evening to get up, Liston's rendition of a coma wouldn't have fooled a possum."
