Everyone is so scared shitless of Jones, nobody has done what they need to do to even test him.
Machida is the only guy in my opinion that has tried to implement his gameplan and try to win. Everyone else has basically sat back looked to land a haymaker and survive.
What I've seen from Jones in glimpses here and there is, if he is pressured, he pulls back straight and while it might not be panic, there is a lapse in his concentration.
This is interesting for two reasons. First, you never just pull back straight from a flurry it just puts you on the end of punches. Two, that he tends to turtle up and duck makes it even worse. So far he has gotten away with it due to his incredible length.
He is constantly improving and he may very well close this gap, but right now I can absolutely see someone who throws caution to the wind, who has the appropriate style, putting him out.
Hendo has the "I don't give a feck" mentality, but I don't know if he has the other tools. He certainly has one shot KO power, but he is the type of guy who won't chase a fight, he will sit on that one big shot.
Maybe the guy who has the tools and the mentality isn't in the division yet. At HW I think he'd beat a lot of guys, I also think he could get blasted quite easily. At LHW the problem is, Jones has not had to face a guy who got in his face, stayed in his face, and pressured him.
Rampage didn't do it. Shogun didn't do it. Rashad didn't do it. Machida isn't a pressure guy, but as I said before, Machida at least TRIED to fight his fight and not just survive.
I remember another guy with an aura of invincibility about him. Nobody thought he could lose till a dude who could take a punch, had nothing to lose, showed up in Tokyo and shocked the world.
