Of course Foreman could catch hm early and finish it, but Tunney was a fantastic mover, ring general, fast and very durable. He also had understated sort of slashing type power that will ensure he gains Foremans respect. It wouldn't be that far off of 60's Ali vs Foreman actually: I just can't envisage Foreman catching Tunney clean that much at all. The first couple of rounds would be an acid test for his chin, though. I know you're a big fan of Walcott, suze I personally think he has all the tools to beat Foreman and reckon he would decision him. How about you? Oh and how do you see Johnson or Langford vs Foreman?
I strugle with his ranking for the same reasons. Another mark against him for me is that on top of having relativley few fights against ranked contenders in his first career he never went beyond 10 rounds. Between the Ali Young and Peralta fights it is as clear as mud how he would have fared in an era with a lot of slick technical boxers. Of course his feat of regaining the title in his mid 40s in unmatched and his demolition of Joe Frazier could easily be called the single best win in heavyweight history. In short I could understand any ranking from 5-15 and perhaps outside that envelope.
I always manage to find a place for him in my top 10, always in the lower half. My top three are absolute locks, really. 1. Louis 2. Ali 3. Marciano Louis and Ali are interchangable, but I can't rate Marciano below #3.
