So they have nearly the same fights to losses ratio, what's your point? Kessler was in more title fights that's it. If you look at quality you can't say one has contributed more than the other. The same people who say Dirrell is an actor and he wasn't really hurt by AA are the people who vote for AA as the hardest puncher. Go figure. What was AA's record before fighting Dirrell? Who did most people pick to win this fight and then the tourney? And NOW after Dirrell exposed AA's flaws and laid the blueprint on how to beat him you're saying he's not a top fighter. Hindsight is 20/20. Siaca, Beyer, Lucas and Andrade are not worldclass fighters. Titles don't mean nothing it's about who you beat for those titles.
