If Mayweather is even near his normal level he will beat Ortiz. I've watched several times carefully the last fights of Ortiz and found him better at all than DLH. Mayweather has weapons to unarmed Ortiz. One of the main reason why Ortiz obviously will lost that fight is his slowness, formal boxing and unability to defend himself. He's like overrated and hyped Fernando Vargas.
