This could actually be an ugly fight if both guys decide they want to sit back and counter.
However, I suspect we've seen the last of that style from Lyoto, so I'm anticipating fireworks.
Lots of the patented Karate feints and twitches from Lyoto, and lots of leg kicks.
I hate to say it, but Hendo will likely be outclassed by a vastly superior/unpredictable striker. Hendo might hit harder as he wings that overhand right, but Machida does everything else better.
