Some of you guys made me laugh. If Pacman beats up a 29-34 year old fighter, he is branded as fighting oldies and past their prime. If Marquez beats up a 37 year old fighter he should be number 1.. What the hell If Pac moves up and beat a recognize belt holder he is branded as fighting the weakest champion (as the case against D. Diaz). But if Marquez beats up and win the fraud belt of Casa(fraud coz it was a gift from Santa Cruz) he is the greatest? You guys are really funny here, like the way you don't give credit to campbell's accomplishment. Campbell beats up a PRIME+MULTIPLE BELT HOLDER fighter. Campbell should be above Pacman and Marquez. Don't reason out like Marquez beat the man who beat Campbell before.. Hey the man who beat Campbell before was a fresher Casa not a 37yr old Casa. If you consider this kind of reasoning, heres another one, Pac beat D.Diaz who knock Santa Cruz out who win on most peoples eye but lost to Casa in a controversial decision. Its sucks right... Lets just wait who clean up the division but for the mean time i give Campbell his credit and rank as the man of the lightweight. He may be a weak champ with many L on his resume but has the credential and wins against credible champs as of press time.
