DC and Aldo both were given the belts and had lost to the previous Champ. The only difference is Aldo is an All time great and still the best there ever was at 145lbs, and the former champ no longer fights there. oh and he has 10+ world title defences. DC won the 2nd hand belt and defended it once in a razor close fight. At least with Aldo, there still is uncertainty of how a longer fight would go with the guy who beat him. DC on the other hand was soundly beaten by Jones and a rematch wouldn't look to different...considering DC is 2 years older into his late 30's than the last fight. I know most people don't care about the rankings, but if they're going to have it...atleast let it make sense.
