Hmm, I was actually thinking about this match up the other day.
I would bet on Silva TKOin' Mr Page. Rampage may have the best chin in the business, but Silva himself has some power in his strikes and has slicker than your average footwork that is more than likely to frustrate The Ramp.
Oh and can we say leg kicks? If the fights with Griffin and Jardine are anything to go by, then Rampage still has a long way to go to improve on his lower body defence, and against another long limbed muay thai bred fighter, he is more than likely to be chopped down to size.
Rampage has very good boxing, conditioning and underrated takedown defence, though. The latter he wouldn't need to worry about with Silva, but if he was able to somehow get Silva to brawl with him and land one of skull cracking hooks then, I don't care how tough your chin is, you are going to get rocked or even dropped.
Also Rampage has decent takedowns and slams, so if he could do that, then there is a chance he could grind out a decision on The Silva Spider. No easy feat considering Silva has proven many times he can fight effectively off his back, but it would be the best chance Page has in a victory.
Why Do We Fall?
