Anybody who went 15 rounds with Palomino ought to qualify, as is the case with Frazier. (Of course only Ali and Bonavena did this with Joe.) Defensive specialists like Benitez, Locche and Young had to be able to take it downstairs. Harry Greb also stood up to frequent body attacks. What's more interesting to me are those few world champions who could not take body punching well. Marvin Johnson is the most prominent example who is a likely future hall of famer that I can think of off the cuff. Mustafa Muhammad and Mike Spinks both deflated Marvin badly with body shots, yet Pops somehow managed to win a third world championship late in his career.
Valuev VS Mirovic (or anybody for that matter). That was a savage but educated body attack that Valuev forced Miro to sustain. I've put together the most brutal highlights for you all, so you can understand the moves and see how damaging yet smart they really are.

Haha, once again I have "When We Were Kings" playing in the background and I click on this thread while the part where Norman Mailer explains the interplay between Foreman, Saddler, the heavybag, and the "watermelon sized dent" Foreman's fist made in the heavybag.
