His punches look scary as fuck.
The way he has that snap with his punches.. I couldn't imagine taking one of those. I'd probably be put in a coma if that guy landed a glancing shot, hell, even if he missed, the air that goes by my head would probably put me to bed. That guy could probably punch a wall and the shockwave would put down an entire suburban area.
He isn't just all raw power either, he clearly is just one of those guys who can just hit hard, they naturally just have that power, but his technique is so damn good and that makes him 100x more dangerous, unlike Roy Nelson. Roy is mostly just a guy with serious raw power, whereas Hunt is a guy that clearly has that natural born raw power as well as great technique, that snap in his punches.. all technique.
To me, it looks like even when Hunt does get very tired, he still throws his punches just as hard and just as quick. He'll get tired, but he'll still try to fight at the same pace. He doesn't really get all zombie-like, like so many other fighters, like Chris Leben or BJ Penn for example.
I love the way he sets up his strikes, too, especially in his fight against Stefan Struve. I remember he was simply just tapping Struve's arms, then a little tiny punch to the body, just to create an opening and as soon as Struve left a little opening, Hunt fired a fucking haymaker at him.
You don't really see many MMA fighters create openings like that. You usually only see this kind of thing in Boxing. The only other fighter I've seen do this a bunch of times was Nick Diaz. They're pretty much just feints, his opponent will put their arms up to block their face and Nick (or some other fighters) will just tap your arms with a couple little punches, or they'll tap the arms a few times and then do one or two to the body and as soon as his opponent drops their hands just a little bit, BOOM, a random power punch to the head.
It's actually pretty fun to watch. The time Hunt did that to Struve is still fresh in my memory, I love seeing fighters mix it up like that, creating little openings like that.
Hunt is a scary dude.
