Even if he did all that, I don't think most boxing historians would rank him ahead of SRR. And doing all of that is a TALL order. That's like saying, "if Klitshko beats Brewester in the rematch, then beats Peter, Vitali, Ivan Drago, Apollo Creed, lures Tyson out of retirement, and then fights MMA and beats Fedor, he'll be an ATG HW".
