Bradley would wear ortiz down,berto isn't a pressure fighter and ortiz can't fight going back,another thing,berto wishes he had bradley's stamina.
Ortiz would beat the hell out him, too big also better technically. Bradley applies good pressure but you need power to make Ortiz respect you and if you don't your only hope is if you're a master boxer type, Braldey doesn't meet either of these criteria, he's a mediocre boxer with no power, Bradley's strangths are his workrate/pressure/will. His pressure would be usesless against Ortiz and would allow Ortiz to trade with him then goodnight!
Bradley would have won. This is maybe the only time that Pacquiao fought a better boxer than Mayweather did in their most recent bouts.
