Hatton is not a true WW and we all know it, hence why he dropped back and down to JWW. DLH had campaigned for years at 154 before draining for the fight. Look, I am a big fan of manny, but the fact remains, we're putting him in fantasy matches against quartey, against margarito, against clottey, etc.. and he hasn't fought anyone natural to 147 yet.
Well, Roy Jones hadn't fought a heavyweight before he fought John Ruiz...I don't know what point you're trying to make.
Pac never fought a Jr.WW before he fought Hatton and look what happened there. He also never fought a featherweight before he fought Barrera.
He hasn't, but he is about to in about 3 weeks. It will be a great test to if he can handle getting hit by natural welters. Or will he be able to avoid big shots and dominate in his style. Either way for him to win would b every impressive. If he can avoid being hit that takes a lot of skill. If he were to get hit and handle the power that would be very impressive as well.
