Why is Jones and Silva the only one who makes sense?
Theoretically they're the exact same fight just at different weights... If silva fought GSP then he'd get wrestle fucked, if silva fought Jones he'd get wrestle fucked.
If GSP stands he'll get done, if Jones stands personally I think he'll get done a la Machida picking him apart in the first round of their fight.
It's the same fight regardless of who's in it. I'd rather see Silva vs GSP.
EDIT - Also which is the only one being talked about? Silva vs Jones isn't.
