This would actually be a good fight for Mayweather at this point. However, he seems to have little interest in fighting anyone at this time.
Why does Ortiz sign the fight this early in his career? Surely too easy to cash out. Although this is quite funny, if it does happen, Ortiz runs his mouth about knowing he'll beat them both, only now he has to back that up.
If they fight, and Ortiz loses, it won't be held against him and no one will say he's washed up due to his opponent. He'll make lots of chavo and will get great experience.
