Styles, peaked/peaking at different times...Pretty straightforward I'd say? Not to mention, lets not pretend that the "everyone else" he beat were as good as Canelo? Arguably the only two guys who had that level of talent were the two he fought immediately prior in Brook and Jacobs, and both of those guys had success against him, Jacobs had a lot for that matter. I think he pretty clearly won the first fight as well, nobody would have batted an eye if the cards were wide for him in that.. The next fight was extremely close and probably took a fair bit out of him. I don't think he has much chance in a third fight if that's still what he's hoping for.
