Let's see here...Foster got clobbered every time he fought a heavyweight and Tunney defeated one of the greatest heavyweight champions of all time. Hmmm....
Not sure what the biggest "heavy" Tunney really beat. Easy to envision a pumped-up 220 lb Max Baer taking Tunney out.
The best Tunney was too skilled for Baer. Certainly an old past prime Tunney fighting Baer in the 30's anything could happen.
Getting back to the posts question, Lewis could take out Bob anytime he wanted to, likely within the first three rounds. Bob might be able to stun Lennox if he could land solidly but thats not very likely, Lewis had the size, strength, and arm length to completely keep Foster at bay until landing with his big right hand, in the first round if he came out with a fire under him.
Lennox would blast foster out of there in less than thirty seconds. It would make tyson v spinks look a hard fight!
I had the chance to talk to Bob foster once and asked him how he would have done against Leon Spinks in his prime. He shook his head and said he never had any luck against heavyweights
Totally disagree. He failed every time he stepped up to HW. Stepping up against Lewis would be a sure fire defeat.
