Imagine boxing was 20 rounds..or 6?

All time I'd probably take Jeanette in the marathon and Saddler in the sprint.

These modern times Cal is a good pick @imp. I'd have to give that category a little more thought. Probably Jofre in the marathon and Tyson in the sprint.

Almost forgot. Interesting question.

I remember calzaghe or his dad saying they never used weights or did any weight training and that impressed me as JC body is not the typical looking toned cut body especially as he looks to have such short arms, but the avoidance of the weights must have contributed to his stamina.
