I think Silva is 'that good'. Didn't he dislocate Forrest's jaw in one of his first punches ? Forrest had nothing in him after that...couldn't punch for chit and Silva knew it and was able to toy with him.
When he did connect it caused Forrest tremendous pain and then the last punch was lights out.
I think the fight is still here...
