Well i think the best fights DLH can fight are at 147 or 154, lets face it hes to small for 160. If he fights Pavlik it would be a very sad ending for Oscar, nobody should go out like that.
Asking DLH to fight Calzaghe is just as crazy as crazy as asking Pac to fight DLH. DLH will not fight PAC.
I would consider those equally as crazy as to ask Haye to fight Hopkins at heavyweight but that doesn't mean it won't happen. All of that means that Boxing has turned into a Goddamn Circus and since any Circus has clowns, somebody has to play that role - De la Hoya just wants others to play as clowns, nothing more.
