Who Will Have The Better Career Bradley Or Khan?

These guys are both the top in the division and they SHOULD have already fought each other this weekend past instead Bradley didnt fight and we got Khan v Judah instead. Khan is 24 and Bradley being 3/4 years older at 28, Both have unified the division, Bradley has done so twice, Bradley remains undefeated and Khan has the loss to Prescott on his record. Khan has fought at lightweight, light welterweight and plans to move the welterweight and might end his career as a light middle weight or middleweight, Bradley has already fought at welterweight against Abregu. In fairness Khan has already earned enough money that he could retire today and never have to fight or be wanting of money, This then begs the question as to why someone who is young and already a multi-millionaire Khan has earned almost $25 million already Bradley has not earned a fraction of that but it might infact work in his favour as the hungrier guy. Who do you think will go further in the boxing world between these two? Leaving the current "ducking" issue aside down the long term who will do better? Personally I think Khan will go further because his build is more suited to going up and down weight divisions, He has Freddie Roach and Ariza, Oscar De La Hoya and RIchard Schaefer are trying really hard to promote him in the US and he trains along side Pacquaio and has a fanbase internationally not just in the UK, but also the middle east, Pakistan and to a lesser extent the Philiphines. But boxing is not a popularity contest!
