Who achieved more, who beat the better opposition, who had the better skills etc. all questions to consider before offering an opinion.
Hamed probably. He fought better opposition and whilst both retired early in their respective careers, Hamed achieved more. Not to disregard Haye though, who unified at CW and did go to heavyweight to win a title and fight the best in the division (eventually). Both came unstuck, Haye against Thompson and Klitschko - Hamed against Barerra. But, overall you'd have to give the nudge to Hamed on this one. Oh, on a side note, I'm watching House Party. So, every post I make tonight will be finished with a quote from the film. It's my cry, two tears in a bucket, **** it, lets take it to the staaaaaagggeee.
Hamed : 35 Haye : 0 This is the first time I see such results. On the other hand the answer is so obvious ...
