I really like both these guys. And I feel like its a coin flip. Chuck has the better KO power, but Silva's has much better hand speed. I'd say Chuck's chin is probably a little better that being said its no so much the power of silva's punches as the sheer speed and volume you get hit with. Silva has great knees and Chuck has great leg strikes. The fight will boil down to can chuck connect while avoiding Wanderlei's bull rush or will Silva's constant pressure and hand speed be the difference. Classic brawler vs counter puncher in terms of boxing.
