There were some questions in some of his fights. The fight against Listen. Listen was going to kill him. Then Ali hit him with the fantham punch that knocked listen out that no one saw. Ali said he hit him with an anchor punch that no one ever saw

Everyone thought listen took a dive I thought that myself.

Then the biggie the fight against foreman in Africa. the ring was fixed so Ali could lean back on the ropes well over 2 feet to keep foremen from taging him when foreman had him against the ropes.that was redicules a joke. Foreman got tired and ran out of gas.
