Yeah, but both got warned, the point being you can't put your head down like peterson was doing, Khan got points deducted for pushing, mayweather used his elbow - which is different. People make out that the ref was fair due to the deductions, but what their missing is that he kept warning khan only, in Floyd vs Castillo the ref warned both - you can argue he was harsh but you can't argue he wasn't fair, he also stopped the action (call break) to warn the fighters unlike cooper who just said it during the action - this isn't a real hard warning
it was a close fight, but everytime people give it to the underdog. It was not a robbery from my point of view.
