Ortiz... But whats your point? It's not like Floyd actually beat Victor in a legit manner! It was a sucker punch. Do you understand that?
Are you high? Ortiz dropped everyone not named Mayweather at least once in every one of his bouts. He's a vicious fighter who has a decent work rate.
Ortiz is more dangerous due to his power.. But Bradley has better pure boxing skills. Take a look at your local sports book... The KING is only a 4-1 favorite over Bradley!
Dangerous? Ortiz by far, if he had the mindset and focus to go with his physical attributes he could go a very long way.
If by dangerous you mean 'most likely to beat you', then I've voted for Bradley. Simply put, he's the better boxer. But if you're talking about who's more likely hurt/KO you, then it's Ortiz, easily. But it all depends on which boxer is facing them. Khan, for example, would have a much harder night with Ortiz. Whereas a Pacquiao, would be more troubled by Bradley.
Ortiz, he was world champion at 147 when Floyd fought him, we don't know how Bradley will look at 147 against an elite opponent.
