I really don't see how Siver wins. Power shot or kick is perhaps the only way.
Any other time when Siver is o teh prelims, no one will talk as if he is legit. Yet when he makes a main card against a relevant fighter, he is all of a sudden a threat. Don't believe the hype, this isn't a close match up.
Soti won't be out-struck, and will eventually sub him. I'll go 2nd round armbar.
