up until the bit about the bear it sounded very much like a perfect description of michael moore in fahrenheit 9/11.
every top level fighter has people who underrate him and people who overrate him. there is very rarely a definitive answer.
Other way around really. Unfortunately America is the world stage for the best fighters, because it brings the most dollars. Proof of this is why now Hatton, and klitschkos have ventured into america for the bigger fights. Guys like Calzhage and Michalzewski had plenty of chances to take on the big fights to advance their P4P standings and chose to stay in their respective countries fighting a long list of nobodies with the occasional shot name fighter. More proof is seen when guys like Hatton win controversially against a fighter like Collazo and Klitschko gets ***** slapped by Brewster. They then wake up and see fighting the "worlds" best requires improvement in their skills. Much props to guys like Hatton and the fighters that actually take the initiative to go out and make the biggest fights.
I agree with you about "thats where the money is", but as for HAVING to go the States to prove yourself, thats only an opinion, mainly from people from within the states, why? I dont know, I dont ***** and moan that SSM, PBF, ODLH arent over here all the time, now before you say it, I know they dont have any particular need to, but in JC and Hattons case, neither did/do they need to, only in your eyes.
