I don't know. I think if you're a powerful wrestler with a knowledgeable stand up game, you're going to make a show of Bigfoot. On his back he turtles up and is open to get smashed. He wont be able to rocket back up to his feet either. You just have to watch out for those surprising heel hooks. He could catch you coming in but if you can move your head and have a bit of speed about you, you should handle it.
Browne seems like a good fighter, and obviously the karate shit is stupid by the way he got owned by a punch in like 5 seconds jumping about like a fairy. If he used his jab a lot more and kept himself out of range, he might have some more success. Maybe if he faught ACTUALLY like Cruz.
