Well Silva already faught at MW twice and I think the combined fight time was less than 2 rounds and 2 overwhelming victories.
Prior to tonights fight, everyone was saying that anyone with any kind of wrestling would be a real problem for Silva, guys like Munoz for example. But I think he proved that wrong tonight.
He could move up, but unless he fights Jones, no one will care. I just don't see him fighting Jones. Jones is a borderline HW. I think it's asking too much of Silva to fight a guy that size. It would be competitively unfair.
I would rather see Silva and GSP at a catch weight.
