Margarito would not be intimidated by mayorga like forrest was. he'l take the fight to him, an make him go backwards where he is ineffective.
As good as Mayorga was, he still fought his best in short bursts. And even his best relied on a home run or intimidation. Neither would work on Margarito. His chin is always tucked and he'll be throwing and hitting no matter what Mayorga does. I don't even know if Mayorga could keep pace, since his bravado in this would likely make him up his pace to trade. That's not his fight. Mayorga would need a KO to beat Margarito, and it's unlikely he'd get it. Mayorga's one punch power is vastley overrated.
