So where do you rate Abraham, he's not to disimilar in those regards...lost on the bigger stage but beat plenty of world title holders.
Abraham didn't beat anywhere near the amount of titleholders as Kessler. Check the records mate. He was also very disappointing away from home comforts, while Kessler showed he could travel. I think Abraham clearly benefited from friendly officiating on a few occasions where he got away with fighting in sporadic bursts.
Kessler is a significantly better fighter at 168 than Abe was at 160.
