If we say that Rock fought until 1959 which would have him retire at 36, and take out the management issues what fights were out there for him to make and how would he have faired? Obviously there is Patterson and Ingemar....Floyd is a great fighter but eventually would get his bell rung after out boxing Rock for several rounds...Ingemar was a slugger and would get KO'd inside two rounds....I think that Liston is to young, who else would have been there from 1955 to 1959 for Marciano to fight, and how is was there anyone out there that could have put an L on his record?
