This is a joke right?
This fight will never happen. The only way Leben will ever get a title shot is if Silva beats Franklin and Leben beats an average opponent to have "The rematch that everyone has been waiting for"...the "retribution".
And his striking is far from top notch, swinging your arms around with your eyes closed is not top notch. Yes he has a lot of power, but a lot of guys have a lot of power, and they arent considered top notch strikers. His striking is sloppy, and any good striker will get through them and knock him out (aka Silva).
